AB  - In an attempt to reuse fibrous textile waste and, at the same time, to address dye pollution
in textile wastewater, waste cotton-based yarn was utilized as a cheap and sustainable adsorbent, as
well as a row material for carbon adsorbent production. Unmodified yarn and cotton-based carbon
adsorbents were used as adsorbents for dye removal from water. Cotton and cotton/polyester yarn
samples underwent thermal modification through carbonization followed by chemical activation
with KOH. Various techniques, including scanning electron microscopy, Fourier transform infrared
spectroscopy, nitrogen adsorption–desorption isotherms, and surface charge determination, were
employed to analyze the morphological and surface characteristics of the cotton-based adsorbents.
Adsorption properties were evaluated by testing the removal of selected cationic and anionic dyes
from water. The impact of temperature, initial pH and concentration of the dye solution, and
contact time on adsorption were investigated, and experimentally obtained data were analyzed using
theoretical models. While carbonization alone did not significantly enhance adsorption properties,
activated samples exhibited high efficacy in removing both cationic and anionic dyes from water.
Despite the negative influence of the polyester component in the carbon precursor on the efficiency
of activated samples in removing methyl orange, the results indicated that activated cotton and
cotton/polyester yarn could be used to prepare highly efficient adsorbents for the rapid removal of
methylene blue from real wastewater samples.

AB  - In this study, waste flax fibers with different levels of cellulosic and noncellulosic components were obtained by oxidative and alkali treatments and used to assess the influence of the fiber’s structural and chemical properties on the biosorption of lead ions. Scanning electron microscopy was used for the characterization of the flax fibers’ surface morphology, while the physicochemical properties of the fibers’ surface were determined by the streaming potential method, and Fourier transform infrared spectroscopy. Alkaline treatment decreased, while oxidative increased the crystallinity index of flax fibers by approximately 10%, due to the changes in the content of cellulosic components. Adsorption of lead ions was studied in detail, including kinetics, isotherms, and thermodynamic parameters analysis. It was shown that the amount and distribution of oxygen-containing groups, originating from cellulosic components, have the highest influence on the adsorption capacity of flax fibers, increasing Langmuir adsorption capacity from 12.76 mg g−1 for untreated to 21.9 and 79.9 mg g−1 for alkali-treated and oxidized fibers, respectively. Obtained negative values of ∆GӨ (−4.874 to −0.807 kJ mol−1) and ∆HӨ (−42.81 to −13.65 kJ mol−1) indicated that the adsorption of lead ions onto flax fibers is a spontaneous and endothermic process, which occurs through electrostatic attraction and ion-exchange. The results presented in this work demonstrate that the waste flax fibers of suitable chemical composition may be used as sustainable and renewable low-cost biosorbents.

AB  - This study aims to investigate the effect of alkalization and chemical coupling methods on the surface
and adsorption properties of waste cotton and cotton/polyester yarns. The simple and cheap alkali treatment was
performed using 10% and 18% NaOH solution, while the chemical coupling method involved combining cotton
and cotton/polyester yarns and fly ash, using sodium carboxymethyl cellulose and sodium alginate as binders.
Morphological and surface characteristics of unmodified and modified cotton and cotton/polyester yarns were
analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy, while adsorption properties were assessed by the removal of lead and cadmium ions from aqueous solution. It was found that chemical
modification with 18% NaOH solution positively affected the adsorption properties of only cotton yarns, increasing the removal efficiency of lead ions up to 75%. On the other hand, modification with fly ash improves the adsorption properties of both, cotton and cotton/polyester yarns, increasing the efficiency in removing lead ions by
using sodium carboxymethyl cellulose, and cadmium ions by using alginate as a binder. Using the chemical coupling method, effective adsorbents are obtained starting from waste yarn, which gives it added value, the amount
of non-degradable waste material can be reduced and the criteria of a cleaner environment and circular economy
can be met.

AB  - Waste hemp and flax fibers, and cotton and cotton/polyester yarns,
available in large quantities from the textile industry, were used as cheap and
effective sorbents for the removal of methylene blue from wastewater. Waste
fibers and yarns were characterized by scanning electron microscopy, Fourier
transform infrared spectroscopy, iodine sorption, water retention, and point of
zero charge, as well as through the determination of crystallinity index and
degree of surface crystallinity. Adsorption of methylene blue was optimized by
examining the influence of contact time, initial concentration, temperature, and
pH value. It was found that the more ordered structure of cotton and
cotton/polyester yarns leads to lower adsorption capacities and better agreement
with pseudo-second order kinetic and Langmuir isotherm model, while the more
heterogeneous structure of flax and hemp fibers show higher capacities for
methylene blue adsorption, better described by the pseudo-first order kinetic and
Freundlich isotherm model. Based on the obtained results, waste lignocellulosic
fibers and yarns can be utilized for the discoloration of wastewater, thereby
solving the problem of waste generated in the textile industry.

AB  - Frequent changes in clothing fashion trends and the furniture industry have led to the excessive consumption of textiles to meet human needs. This leads to an increase in the production and finishing of textile materials, and the generation of large amounts of waste, making the textile industry one of the main polluters of the environment nowadays. Therefore, there are concerns about the reckless disposal of chemical and solid textile waste (natural or synthetic yarns, fibers, pieces of clothing, etc.) which can cause serious soil, water, and air pollution. To reduce the amount of waste generated in the industry, and preserve the environment and human health, it is necessary to apply modern trends of sustainable development.

abstract = "Frequent changes in clothing fashion trends and the furniture industry have led to the excessive consumption of textiles to meet human needs. This leads to an increase in the production and finishing of textile materials, and the generation of large amounts of waste, making the textile industry one of the main polluters of the environment nowadays. Therefore, there are concerns about the reckless disposal of chemical and solid textile waste (natural or synthetic yarns, fibers, pieces of clothing, etc.) which can cause serious soil, water, and air pollution. To reduce the amount of waste generated in the industry, and preserve the environment and human health, it is necessary to apply modern trends of sustainable development.

AB  - In an attempt to reuse fibrous textile waste, and at the same time to reduce its quantity, waste cotton-based yarn was used as a cheap and sustainable precursor for carbon adsorbents production. Cotton and cotton/polyester yarn samples were carbonized using hydrothermal and classical carbonization and activated using KOH as activating agent. Nitrogen adsorption-desorption isotherms, scanning electron microscopy, Fourier transform infrared spectroscopy, and Boehm titration methods were used to analyze the structural and surface properties of obtained carbon samples. The adsorption properties of cotton-based carbon materials were tested through the adsorption of selected organic dyes from water. The influence of contact time, initial concentration, and pH value of adsorbate solution on adsorption was examined and experimental data were processed by theoretical models. It was found that the adsorption properties of carbonized samples were negatively affected by the presence of a polyester component in the precursor structure. Nevertheless, the cotton-based carbon adsorbents obtained by carbonization, and subsequent activation proved to be highly efficient adsorbents for organic dye removal from water.

AB  - In an attempt to reuse fibrous textile waste, and at the same time to reduce its quantity, waste hemp and
flax fibers, and cotton yarn were used as cheap and sustainable adsorbents for the removal of pharmaceuticals
from water. In order to improve their adsorption properties, waste fibers, and yarn samples were modified using
18% NaOH solution. Morphology, surface chemistry, and structural characteristics were examined through scanning
electron microscopy, Fourier transform infrared spectroscopy, degree of surface crystallinity, and crystallinity
index. Adsorption properties were analyzed through the determination of iodine sorption and water retention, as
well as, the adsorption of selected sedatives. Modification with 18% NaOH increased the content of amorphous
areas in examined fibers and yarn samples, improving their adsorption characteristics. Utilization of both unmodified
and modified samples enables fast and highly efficient removal (adsorption efficiency ranging from 75 to
100%) of sedatives from water, making waste hemp and flax fibers and cotton yarn samples promising adsorbents
for water treatment.

AB  - This paper attempts to summarize the historical facts about the
cultivation and use of hemp in the world, and especially in Serbia, with a special
emphasis on the research and new application brought by the renaissance of hemp
production at the end of the 20th century. Hemp (Cannabis Sativa L.) as one of the
oldest cultivated plants represents a renewable and sustainable source of fibers, mainly
for textile production. Due to their specific chemical composition, structure and
properties, such as high specific strength, non-toxic, biocompatible and biodegradable
nature, hemp fibers become ideal candidates for a wide range of applications. Being
lignocellulosic, hemp can be used alone, or as combined with different kinds of polymers
to provide a wide range of useful composites in textiles, construction, automotive
industry, and soil conservation. Also, hemp fibers have proven to be efficient biosorbents
and suitable precursors for the production of low-cost carbon materials for adsorption
applications.
AB  - U ovom radu su sumirane istorijske činjenice o gajenju i upotrebi
konoplje u Srbiji i svetu, sa posebnim osvrtom na istraživanja i nove primene sa
renesansom konoplje krajem 20. veka. Konoplja (Canabis Sativa L) je jedna od
najstarijih gajenih biljaka, i predstavlja obnovljiv i održiv izvor vlakana, uglavnom za
tekstilnu industriju. Zbog svog specifičnog hemijskog sastava, strukture i svojstava, kao
što su visoka specifična čvrstoća, netoksičnost, biokompatibilnost i biorazgradivost,
vlakna konoplje imaju visok potencijal za primenu u različitim oblastima. Sama, ili kao
kompozit u kombinaciji sa različitim vrstama polimera, konoplja nalazi primenu u
oblastima tekstila, građevinarstva, automobilske industrije, očuvanja životne sredine.
Takođe, vlakna konoplje su se pokazala kao efikasni biosorbenti i pogodni prekursori za

AB  - The study was aimed at determining the most suitable irrigation schedule program for hemp grown for fibers by using evaporation from the free water surface (Eo), measured by a Class A pan and related crop plant coefficient (Kc). The experiment, carried out in Vojvodina, a northern part of the Republic of Serbia, included three irrigation regimes: I1, I2, and I3 corresponding, respectively, to daily evaporation from an open water surface (Eo), two interrow spacings: RS1 (12.5 cm) and RS2 (25 cm), and topped (T) and not topped (NT) variants. The Kc values used for the calculation of daily evapotranspiration (ETd) were 0.42 for April and May and 1.00 (I1), 0.80 (I2), and 0.60 (I3) from June to the harvest. In addition, the nonirrigated (Io) control variant was also included in the trial. The dioecious fiber hemp variety Marina was used for the trials. Irrigation was carried out by a drip irrigation system and was scheduled based on the water budget method. It started when readily available water (RAW) in the soil layer of 0.4 m was completely depleted by the plants. In the first year of the study, irrigation did not influence the yield of hemp fiber, but in the second one, the best result was achieved for the irrigation variant I1. Interrow spacing did not have a statistically significant effect on both the hemp fiber yield and the quality. The topping of plants significantly decreased the yield of hemp, and it is not recommended when the hemp is cultivated for fibers. The quality of the hemp fibers was not influenced by irrigation, inter-row spacing, and topping. The rate of hemp evapotranspiration was in an interval of 312 mm (ETa) to 520 mm (ETm). The highest values of IWUE and ETWUE in both years and the bark yield in the first year were detected for the I3 irrigation variant, which suggested that the crop plant coefficient (Kc) of 0.6 could be recommended for the correction of Eo values in the calculation of the daily evapotranspiration of hemp (ETd) from June to August. The yield response factor (Ky) with values of 0.22 and 0.60 for the total growing season reveals that, in rainy years, hemp for fiber production could be grown without irrigation in the temperate climate of the Vojvodina region. However, such years are rare. Without doubt, irrigation of fiber hemp is recommended in the mentioned region in order to obtain high yields of good quality product.

AB  - Different natural fibers and yarns (hemp, flax, and cotton), obtained as a waste from textile industry,
were used for the removal of methylene blue from aqueous solution. In attempt to increase the
adsorption efficiency, examined fibers and yarn were modified by sodium hydroxide solution.
Characterization of examined samples was performed by scanning electron microscopy and Fourier
transform infrared spectroscopy. It was shown that applied modification caused the differences in the
distribution of hemicelluloses in the structure of examined fibers and fibers in yarn, inducing the
changes in morphology and surface chemistry. These changes slightly improved the adsorption
properties of hemp fibers, while in the case of cotton yarn modification had a negative effect on
methylene blue adsorption. Nevertheless, adsorption efficiency of these waste fibers and yarns highly
increase with the pH of the solution, enabling their utilization for methylene blue removal from
wastewaters.

In attempt to increase the adsorption efficiency, cotton/polyester yarn was modified by sodium hydroxide solution. Characterization of examined yarns was performed by scanning electron microscopy, Fourier transform infrared spectroscopy and streaming potential method for determination of the isoelectric point. It was shown that applied treatments slightly affected the surface acidity due to increased availability of ester groups and changes in cellulose-derived groups. These changes in surface chemistry of modified cotton/polyester yarns did not improve their adsorption capacity for Cd(II), Cr(III) and As(V) ions. However, both unmodified and modified waste cotton/polyester yarns could be used for efficient removal of lead ions from wastewater.

AB  - Hemp fibers with different amount of hemicelluloses and lignin were subjected to atmospheric pressure dielectric barrier discharge under different conditions (40 W and 80 W power of discharge, const. time 120 s) in order to study influence of plasma treatment on their structure and sorption properties. Wettability of plasma treated samples, compared with precursors, increased due to the changes in hemp fiber surface chemistry confirmed by ATR FTIR spectroscopy and increased roughness as a consequence of intensive surface etching, observed by SEM. After plasma treatment, wettability was the highest for hemp fibers with lower content of hemicelluloses (increase up to 9 times), while wettability of raw hemp fibers and fibers with lower content of lignin increased about 5 and 2 times, respectively. This investigation shows that plasma can be successfully used for improvement of raw hemp fibers wettability, even to substitute the chemical treatment for some applications of hemp.

AB  - In this study, waste cotton yarn was used for the removal of Pb (II), Cd (II), Cr (III), and As (V) from aqueous solution. Adsorption of heavy metal ions was tested from single ion solutions, while competitive studies were performed using two- and four-ion mixtures. In order to change the structure of the material, cotton yarn was modified by sodium hydroxide solution. The surface of raw and modified cotton yarn were characterized using scanning electron microscopy, Fourier transform infrared spectroscopy, and streaming potential method for determination of an isoelectric point. Sorption studies were performed on the basis of pH, kinetics, isotherms, and desorption results. It has been shown that waste cotton yarn modification, typically, does not improve the sorption capacity of the material and that the unmodified material could be used for the removal of examined heavy metal ions. Selectivity was in order Pb  gt  Cd  gt  Cr  gt  As. Desorption studies have indicated to the possible reusability of the sorbent only in the case of Pb removal. A potential application of spent waste sorbent for the soil quality improvement has been considered.

AB  - The paper gives an overview of the current state in the field of natural and chemical cellulose fibers, as well as future prospects of these fibers. While there is a strong expansion of the synthetic fibers industry, world production and consumption of natural and chemical cellulosic fibers were stabilized at certain level with small oscillation in the last few years. Cotton production reaches average level at 25 mil.ton, flax production at 0.8 mil. ton, hemp production at 0.07 mil.ton and jute production at 3.3 mil.ton, while chemical cellulosic fiber production reaches average level at 6 mil.ton. It is expected that cellulose fibers only for clothing, will be in demand up to 40 mil.ton in the year 2050 due to growing market of hydrophylic fibers and tendency to develop production of natural, light, renewable and biodegradable fibers. In this regard, bast fibers, such as flax, hemp, jute, ramie, etc., isolated from plants that cause little or no detrimental effect on the ecosystem, acquire enormous significance. Their modification and conversion into novel value-added products have been discussed.
AB  - U radu je prikazano sadašnje stanje u oblasti prirodnih i hemijskih celuloznih vlakana, kao i očekivanja vezana za ova vlakna. U poređenju sa ekspanzivnim razvojem sintetizovanih vlakana, svetska proizvodnja i potrošnja prirodnih i hemijskih celuloznih vlakana se stabilizovala na određenom nivou: proizvodnja pamuka oko 25 mil.tona, lana 0,8 mil.tona, konoplje oko 0,07 mil.tona, jute oko 3,3 mil.tona, a hemijskih celuloznih vlakana na nivou od oko 6 mil.tona. Očekuje se da će do 2050.god, zahvaljujući rastućem tržištu hidrofilnih vlakana i tendenciji ka razvoju proizvodnje lakih, prirodnih, obnovljivih i biorazgradivih vlakana, potrebe za ovim vlaknima, samo u oblasti odevnog tekstila, dostići nivo od oko 40 mil.tona. Posebno je analiziran potencijal vlakna iz like (lan, konoplja, juta, ramija), njihovo modifikovanje i konverzija u nove proizvode visoke dodate vrednosti, s obzirom da biljke iz kojih se ova vlakna izoluju, kao i sam proces njihove prerade, nemaju negativni uticaj na ekosistem.

AB  - In this paper the possibility of implementing the new biosorbent composed of chemically modified short hemp fibers impregnated with alginate gel for adsorption of lead(II) and zinc (II) ions was investigated. Waste hemp fibers, alkaly treated, were used as an alginate carrier in order to improve the mechanical stability of alginate. Morphological characteristics of obtained alginate-hemp composite were investigated by scanning electron microscopy (SEM), while the Fourier transform infrared spectroscopy (FT-IR) was used for examination of surface chemistry. Alginate immobilization on the hemp fibers surface leads to the morphological changes, by decreasing the roughness of short hemp fibers. FT-IR analysis showed that surface chemistry was changed after alginate immobilization, primarily by increasing the amount of carboxyl groups. The presence of surface groups characteristic for hemp fibers, on the surface of biocomposite, indicate that the surface of hemp fibers is not completely covered by alginate. Adsorption characteristics of alginate-hemp biosorbent were examined through the adsorption of lead and zinc ions, and compared with the adsorption characteristics of alkali treated hemp fibers. Biosorption of lead and zinc ions onto both hemp fibers and alginate-hemp composite, represent fast process since 80 % of initial ions amount were adsorbed in first five minutes. Obtained adsorption data were analyzed by Lagergren pseudo-first and pseudo-second order kinetic models, as well as intraparticle diffusion model. It was found that biosorption of lead and zinc ions on alkali treated hemp fibers and alginate-hemp composite obey the pseudo-second order adsorption kinetics, indicating that adsorption/binding of ions is mediated by chemical forces rather than physical forces of attraction. This observation was confirmed by results of FT-IR analysis of alginate composite surface before and after ions adsorption. It was found that lead and zinc ions predominantly bind on carboxyl and hydroxyl groups through the ion-exchange and surface complexation. New biosorbent demonstrated effective removal of the ions, with the possibility of further process optimization in order to increase the adsorption capacity and rate of metal ions removal.
AB  - U ovom radu ispitana je mogućnost primene novog biosorbenta, na bazi kratkih hemijski modifikovanih vlakana konoplje impregniranih alginatnim gelom, za adsorpciju jona olova(II) i cinka(II). Biosorbent na bazi alginata i alkalno tretiranih vlakana konoplje okarakterisan je sa aspekta strukture i morfologije primenom skenirajuće elektronske mikroskopije (SEM) i prirode funkcionalnih grupa korišćenjem infracrvene spektroskopije sa Furijeovim transformacijama (FT-IR). Adsorpcione karakteristike ovog kompozita, ispitivane su praćenjem kinetike adsorpcije jona olova i cinka, i upoređene su sa adsorpcionim karakteristikama alkalno tretiranih vlakana konoplje. Podaci dobijeni tokom adsorpcije, testirani su korišćenjem Lagergrenovog modela pseudo-prvog reda i pseudo-drugog reda, kao i modela intračestične difuzije. Slaganje modelnih i eksperimentalnih podataka pokazuje da adsorpcioni proces prati kinetiku pseudo-drugog reda, što upućuje na zaključak da tokom adsorpcije jona olova i cinka na površini ispitivanih uzoraka konoplje i kompozita alginat-konoplja, preovladava mehanizam hemisorpcije. Ova zapažanja su potvrđena i rezultatima FT-IR analize, koji pokazuju da se joni teških metala vezuju na karboksilnim, i delimično hidroksilnim grupama prisutnim na površini ispitivanog biokompozita. Na osnovu dobijenih rezultata zaključuje se da se novi biosorbent može uspešno koristiti, kao jeftin i efikasan adsorbent za uklanjanje jona teških metala iz vode.

AB  - In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption properties of flax fibers. The flax fibers were characterized using FTIR spectroscopy and FESEM microscopy, and by determination of chemical composition, carboxyl group content, electrokinetic and sorption properties. Adsorption of silver ions was used to evaluate flax fiber sorption properties, but also to obtain antimicrobial fibers whose antimicrobial activity was tested against Gram-negative bacteria Escherichia coli, Gram-positive bacteria Staphylococcus aureus and fungi Candida albicans. The progressive removal of hemicelluloses or lignin influenced the sorption properties through the increased liberation of elementary fibers and accessibility of functional surface groups of flax fibers. Removal of hemicelluloses led to increase of iodine sorption without significant change in functional groups content and electrokinetic properties. On the other hand, lignin removal led to an increase of functional groups content, namely carboxyl groups, which in turn influenced better moisture and silver ions sorption. Flax fibers with incorporated silver exhibit fair antimicrobial activity against Gram (-) E. coli, Gram (+) S. aureus and fungi C. albicans.

AB  - Waste hemp (Cannabis sativa) fibers were used as sustainable and renewable raw materials for production of low-cost biocarbon sorbent for heavy metals removal. Carbon precursors of different chemical composition were obtained by oxidative and alkaline treatments of hemp fibers. Influence of lignocellulosic precursor chemical composition on hemp fibers-based biocarbon (HFB) characteristics was examined by BET surface area measurement, scanning electron microscopy and mass titration. It was found that lignin content and polymorphic transformation of cellulose increase the SBET of microporous HFBs, while hemicelluloses induce more homogeneous distribution of adsorption active sites. Heavy metal ions adsorption onto HFBs is primarily influenced by the amount of surface oxygen groups, while specific surface area plays a secondary role. Equilibrium data obtained for lead ions adsorption were analyzed by different nonlinear adsorption isotherms, and the best fitting model was chosen using standard deviation and Akaike information criterion (AIC

AB  - By varying the parameters of carbonization and activation, different samples of hemp fibers based activated carbon were obtained. Optimal production conditions were selected based on the adsorption properties of activated hemp fibers toward pesticides. Therefore, the influence of production conditions on the specific surface area, measured by dynamic method, and adsorption characteristics of activated hemp fibers toward different pesticides (acetamiprid, dimethoate, carbofuran and atrazine) was examined. Decrease of pesticide concentration, as a consequence of the adsorption, was determined by liquid chromatography-tandem mass spectrometry technique. Based on obtained results, an efficient pesticides sorbent can be produced using: carbonization temperature of 1000 oC, activated agent/carbon material ratio of 2/1 and activation temperature of 900 oC. Additionally, activated hemp fibers impregnated with silver proved to be suitable for water disinfection due to the strong antimicrobial activity against Escherichia coli, Staphylococcus aureus and Candida albicans.

AB  - Oxidized cellulose has a long history of safe and effective use in medical applications. In this paper, research has been directed towards obtaining hormone-active cellulose fibers in the form of an artificial insulin depot, and examination of its biocompatibility regarding cytotoxicity, sensitization, and irritation. The procedure of obtaining the fibrous insulin depot is based on the modification of cotton fibers with sodium periodate, followed by chemisorption of insulin from insulin aqueous solutions. In order to optimize the insulin chemisorption process, the influence of the fiber structure parameters, i.e. the aldehyde group content and iodine sorption value (ISV) on the chemisorption capacity was examined. The obtained artificial depot, containing approximate to 55 mg insulin/g of fibers, has been characterized in vitro by investigation of the desorption kinetics of the insulin from the fibrous depot. It has been shown that insulin is controllably released in quantities of 1.3-1.6 mg of insulin during 24 hours, in the course of 20 days. The results of biocompatibility tests have shown that the examined artificial depot neither shows irritating effects nor provokes sensitizing or cytotoxic effects. Therefore, these materials are acceptable for use in a direct contact with tissue of a living organism.

AB  - Hemp (Cannabis sativa) was most likely the first plant cultivated by mankind for its textile use. Currently, the interest in hemp is focused on its use as a raw material for the production of environmentally friendly clothes, technical textiles and composite materials. The increased production of hemp fibers in textile industry brings the considerable amount of waste in the form of short and entangled fibers. The cost of waste disposal can be minimized by recycling the waste in the way of producing useful lowcost products. Following the general trend of finding low-cost and easily available adsorbent, waste short and entangled hemp fibers were utilized as a heavy metal biosorbents. Due to the specific structure and heterogenous chemical composition (cellulose, hemicelluloses, lignin, pectin), short hemp fibers as biosorbent offer an effective way to decrease Pb2+, Cd2+ and Zn2+ ion concentration in wastewaters. The influence of hemp fiber chemical composition on their heavy metal ions sorption potential, were assessed by evaluating the water and metal ions uptake capacities of differently modified hemp fibers. The process of heavy metal ions biosorption on short hemp fibers was clarified by mathematical model development. Proposed mathematical model provides a better insight into phenomena of different ions transport through porous fiber matrices, and possibility of optimization of the complex process of biosorption. This is from great importance in the case of using short hemp fibers as filter material for removing the heavy metal ions from polluted water. Furthermore, there is a growing interest in using different type of waste biomass for production of carbon materials as a sorbents for water purification. From that aspect, short and entangled hemp fibers were used as low-cost precursor for production of carbon materials. Chemical modification of hemp fibers, prior to carbonization, affects the specific surface area, amount of surface oxygen groups and morphology of carbonized hemp fibers. Furthermore, activation of carbonized materials with potassium hydroxide improves sorption properties of carbonized hemp fibers by increasing the specific surface area (up to 2192 m2/g) and amount of surface oxygen groups. Due to the good adsorption properties toward heavy metals and pesticides, carbonized and activated hemp fibers were successfully used as a sorbent for the purification of water polluted with pesticides and heavy metals. Also, activated hemp fiber sorbent used for analyte preconcentration in the solid-phase extraction procedure (SPE) for pesticide analysis in water samples, showed even higher efficiency in pesticides preconcentration than expensive commercial cartridges. Sorption process of heavy metal ions and structural parameters of carbonized hemp fibers were described by upgrading already proposed mathematical model. A good agreement between model prediction and the experimental data indicates that the proposed mathematical model can be used for optimization of heavy metal ions adsorption process by correlating the model parameters to the carbonized hemp fibers performances.

Proposed mathematical model provides a better insight into phenomena of different ions transport through porous fiber matrices, and possibility of optimization of the complex process of biosorption. This is from great importance in the case of using short hemp fibers as filter material for removing the heavy metal ions from polluted water. Furthermore, there is a growing interest in using different type of waste biomass for production of carbon materials as a sorbents for water purification. From that aspect, short and entangled hemp fibers were used as low-cost precursor for production of carbon materials. Chemical modification of hemp fibers, prior to carbonization, affects the specific surface area, amount of surface oxygen groups and morphology of carbonized hemp fibers. Furthermore, activation of carbonized materials with potassium hydroxide improves sorption properties of carbonized hemp fibers by increasing the specific surface area (up to 2192 m2/g) and amount of surface oxygen groups. Due to the good adsorption properties toward heavy metals and pesticides, carbonized and activated hemp fibers were successfully used as a sorbent for the purification of water polluted with pesticides and heavy metals. Also, activated hemp fiber sorbent used for analyte preconcentration in the solid-phase extraction procedure (SPE) for pesticide analysis in water samples, showed even higher efficiency in pesticides preconcentration than expensive commercial cartridges. Sorption process of heavy metal ions and structural parameters of carbonized hemp fibers were described by upgrading already proposed mathematical model. A good agreement between model prediction and the experimental data indicates that the proposed mathematical model can be used for optimization of heavy metal ions adsorption process by correlating the model parameters to the carbonized hemp fibers performances.",
