AB  - Adsorptive, catalytic, and antibacterial properties of clinoptilolite-rich tuffs (ZT) are presented here. ZT transformed into Fe-containing ZT (Fe-ZT) removes various organic and inorganic anions from water. Fe-ZT, which contains selenium, is beneficial for growing Pleurotus ostreatus mushrooms. The fungi convert inorganic Se from Fe-ZT into a more useful organically bonded form. ZT and Fe-ZT as supplements retain nitrogen and potassium in sandy, silty loam and silty clay soils. ZT shows an affinity toward toxic metal cations, which are essential for cleaning contaminated water. The adsorption of atenolol, acetylsalicylic, and salicylic acid onto M-ZT (M–Cu2+, Mn2+, Ni2+, or Zn2+) from water solutions suggests that both the natures of M and pharmaceuticals have a significant impact on the adsorption mechanism and determine the adsorption capability of the ZT. ZT is an excellent carrier for ultrafine (2–5 nm) nano oxide particles, which have been shown to have catalytic activity in different chemical processes and photodegradation reactions of organic pollutants. ZT can also be transformed into SO4-SnO2-ZT, which is catalytically active as a solid acid. M-ZT is an effective carrier of valuable bacteria. Ag-ZT possesses beneficial bactericidal activity in disinfecting water and soil remediation.

AB  - Due to their unique structural properties, low cost and environmental compatibility, natural zeolites have been recognized as effective
supports for photocatalytic particles such as transition metal oxides (e.g. TiO2, NiO, ZnO, CuO, SnO2, Fe2O3) in the catalytic degradation
of complex organic dyes present in water media [1, 2]. The lattice of zeolite prevents the aggregation of oxide species but also
contributes to the electron-hole recombination. It has been noticed that pure clinoptilolite (CLI) exhibits a photocatalytic activity in the
degradation of rhodamine B. This is explained by the presence of Ti and/or Fe species, which are usually impurities in zeolitic tuffs [3].
The present study focuses on CLI-rich natural zeolitic tuffs and their photocatalytic activity in the degradation of cationic organic dyes
such as methylene blue (MB). CLI from different regions and deposists was tested: a) Serbia – Slanci (SCLI), b) Turkey – Gördes (TCLI),
c) Iran – Semnam (ICLI), d) Romania – Baia Mare (RCLI) and e) Slovakia – Nižný Hrabovec (SKCLI). Samples were sieved to obtain the
particles with the size in the range 63 and 125 μm mesh, washed with deionized water, dried at 105 °C overnight and tested wi thout
any additional treatments. Photodegradation tests were performed using a batch reactor system equipped with a 50 cm3 Pyrex glass
cell and by a circulating water jacket to keep the constant temperature at 25 °C. All tests were done at atmospheric pressure. Suspension
contained water solution of MB (C0= 10 mg dm–3) and photocatalyst in the concentration of 0.2 g dm–3 at different pH (pH= 3, 6, or
9), was continuously stirred by magnetic stirrer for 30 min to achieved an adsorption/desorption equilibrium and then irradiated for
300 min. Osram Ultra Vitalux lamp (300 W) served as visible light source, positioned 10 cm above the photocatalytic reactor. The
concentration of MB was measured colorimetrically at λ = 664 nm by using an UV/VIS spectrometer.
The obtained results showed that the overall degradation of MB by the photocatalytic process can be attributed to the joint effect of
initial adsorption and degradation under visible light irradiation. The adsorption amounts indicated that CLI has two roles: adsorption
of MB during the dark phase and photocatalytical. The adsorption increased with pH. The photocatalytic degradation is also affected
by pH showing the best activity for all studied zeolitic tuffs at pH= 6. The rate of MB degradation varied from about 36-47% while the
total degradation was 70-91%. The photocatalytic activity was attributed to the presence of Fe species showing a linear increase with
the Fe content in the tuffs. The MB photodegradation follows the Langmuir–Hinshelwood kinetic model. The recyclability tests showed
that the degradation rate decreased from 91 to 69% during three reaction cycles, demonstrating a promising potential of CLI in the
treatment of textile industry wastewaters.

AB  - The use of antibiotics constantly increases which has a notable negative impact on water bodies. Ciprofloxacin (CIP) is widely applied
antibiotic in both human and veterinary medicine, as well as in a livestock breeding. Due to its extensive use, CIP has been found in
wastewater effluents in a wide concentration range from ng to mg dm^(–3). An extremely high concentration of up to 50 mg dm^(–3)
has been found near drug manufacturing plants [1]. Since CIP, as well as many other pharmaceuticals, cannot be efficiently removed
from wastewater streams by conventional wastewater treatments, it is of a great importance to find an acceptable method for their
removal.
This study reports the use of natural calcium-rich clinoptilolite (CLI) for the adsorption of CIP and regeneration of the spent adsorbent
(CLI-CIP) by non-thermal atmospheric pressure plasma (NTP). The results show that the CLI possesses a high adsorption efficiency in
removal of CIP at 283, 288 and 293 K in a slightly acidic medium (pH= 5) for the initial concentrations from 15 to 75 mg dm^(–3). The
CIP adsorption by CLI follows the Lagergren’s pseudo-second-order kinetics and it can be described well by the Langmuir isotherm
model. For all studied temperatures and initial concentrations more than 85% of the CIP is removed within the first 10 minutes. The
results also indicate that the CIP adsorption mechanism includes two phenomena: 1) electrostatic interactions between negatively
charged aluminosilicate lattice and cationic form of CIP species and 2) ion-exchange reaction.
The use of NTP for the regeneration of CLI-CIP was based on the assumption that NTP generates highly reactive species which can
induce a cleavage of the bonds formed between active sites on the CLI surface and CIP, and also induce the CIP decomposition. The
NTP treatment was performed for a short time, with a low energy consumption, and without using the additional chemicals. All these
make the procedure acceptable not only from economical point of view but also regarding environmental issues [2].
A surface dielectric barrier discharge plasma source was used for the treatment of CLI-CIP. The regeneration study was consisted of five
successive adsorption/NTP cycles. Powder X-ray diffraction and Brunauer–Emmett–Teller surface area analyses confirmed that the
plasma treatment did not influence the CLI lattice nor its textural properties. Moreover, X-ray photoelectron spectroscopy confirmed
that the NTP reduces carbon content in the regenerated CLI for more than 90% and that the plasma reactive species are involved in the
CLI regeneration process.
The obtained results strongly support the applicability of the NTP treatment in regeneration of zeolite-based adsorbents used in
pharmaceutical removal from wastewater.

AB  - Research background. In the recent years, considerable attention has been given to selenium status since its deficiency is linked with various disorders and affects at least 13 % of world population. Additionally, mushrooms are known to possess pronounced capacity for absorption of various micronutrients, including Se, from soil/substrate. Here, we investigate the possibility of using Se-rich zeolitic tuff as a supplement for production of selenized mushroom. Furthermore, the impact of the enrichment on the activity of anti-oxidant enzymes and biological potential of Coriolus versicolor medicinal mushroom is studied. Experimental approach. Se(IV)-and Se(VI)-modified natural zeolitic tuff from the Ser-bian deposit Zlatokop was used as supplement for mushroom cultivation. To examine the effectiveness of selenium enrichment, we determined total selenium with inductively coupled plasma mass spectrometry (ICP-MS), together with the activity of antioxidant enzymes in fresh fruiting bodies and biological potential of methanolic extracts. Antioxidant activity was evaluated using the appropriate tests for: inhibition of lipid peroxidation, DPPH free radical scavenging assay, Fe(III)-reducing antioxidant power assay and ability of chelating Fe2+ ions. The antibacterial activity against foodborne pathogens was measured by broth microdilution assay. Additionally, chemical composition of the prepared extracts was studied using UV-Vis and Fourier transform infrared (FTIR) spectroscopy. Results and conclusions. Content of selenium detected in biofortified C. versicolor was even 470 times higher than in control on dry mass basis ((140.7±3.8) vs (0.3±0.1) µg/g), proving that Se-rich zeolitic tuff is an excellent supplement for mushroom production. Furthermore, the results of monitoring the activity of antioxidant enzymes revealed that most of the Se-enriched mushrooms exhibited higher superoxide dismutase (SOD) and catalase (CAT) and lower glutathione peroxidase (GSH-Px) activities than control. Due to higher amounts of enzymes, which can quickly catalyze the reduction of superoxide radicals, the quality of selenium-enriched mushrooms is preserved for a longer period of time. Investigation of biological potential indicated that Se-enriched mushroom methanolic extracts, generally, expressed enhanced antioxidant properties. Additionally, extracts showed antibacterial activity against all tested pathogenic microorganisms. Novelty and scientific contribution. Cultivation of mushrooms on Se-enriched zeolitic tuff is a new technological approach for obtaining Se-fortified food/supplements with enhanced antioxidant and antibacterial activities.

AB  - Natural clinoptilolite (CLI) exhibited a high efficacy in ciprofloxacin (CIP) removal from aqueous solution by adsorption. However, the regeneration of the spent adsorbent was a challenge since the adsorption occurred via electrostatic interactions and ion-exchange reaction. Herein, the feasibility of non-thermal plasma (NTP) was studied for the regeneration of ciprofloxacin-containing clinoptilolite (CIP-CLI) in five successive adsorption/NTP regeneration cycles. The NTP treatments were performed using a surface dielectric barrier discharge (SDBD) operating at atmospheric pressure in air. Plasma discharge gap, sample mass, and electrode surfaces were varied to find optimal regeneration parameters. For the plasma source with an electrode surface of 37.2 cm2, the 2 mm electrode gap and 20 min of plasma treatment were found as optimal parameters (sample mass of 0.2 g). The plasma treatment did not affect clinoptilolite features which were concluded from a study of textural properties and powder X-ray diffraction (PXRD) analysis. X-ray photoelectron spectroscopy (XPS) showed a decrease of total carbon content with around 10% of carbon residual left on the surface. The CLI adsorption capacity can be regenerated to at least 90% of its initial capacity during the five successive cycles, showing the involvement of plasma reactive species in decomposition of adsorbed CIP.

AB  - The present study focuses on clinoptilolite (CLI)-rich natural zeolitic tuffs and their photocatalytic activity in the degradation of cationic organic dyes. CLI from different regions was tested in the photocatalytic degradation of methylene blue (MB) as a model cationic dye. The photocatalytic tests were performed at room temperature and atmospheric pressure under visible light irradiation. For all the CLI samples, the highest activity was observed at pH = 6. Total MB degradation varied between 70 and 91% (C0 = 10 mg dm–3, 0.2 g dm–3 of photocatalyst, during 300 min). It is suggested that the presence of Fe species in the studied tuffs is responsible for the photocatalytic activity. The activity increases linearly with the Fe content in the tuffs. The MB photodegradation follows the Langmuir–Hinshelwood kinetic model. The recyclability tests showed good stability and efficiency of the photocatalyst. The degradation rate decreased from 91 to 69% during three reaction cycles, indicating a promising potential of natural zeolites in the treatment of textile industry wastewater.

AB  - Novel composites based on natural zeolite-clinoptilolite and monoterpene phenols-thymol and carvacrol were prepared by supercritical solvent impregnation (SSI) in supercritical carbon dioxide (scCO(2)) at 30 MPa and 35 degrees C during 18 h. The content of phenols in composites (thymol-23.0 and carvacrol-19.1 wt%) was determined using both C,H,N and thermal analysis (TGA); interactions of the phenols with the zeolite lattice studied by Fourier transform infrared spectroscopy (FTIR) and powder X-ray diffraction (PXRD) showed that the zeolite lattice was preserved in the composites. The composites exhibited antibacterial activity toward Gram-negative bacteria Escherichia coli DSM 498 and Gram-positive bacteria Staphylococcus aureus ATCC 25923 in different water media (phosphate buffer solution, spring water and lake water). After 1 h carvacrol-containing clinoptilolite showed better antibacterial activity than composite with thymol. Both composites expressed bactericidal effect after 24 h of contact. Leaching of the phenols from composite in water was more pronounced from thymol (22.7-32.1%) than for carvacrol (6.2-8.9%) suggesting influence of steric effect on the desorption process.

AB  - The adsorption of the antibiotic ciprofloxacin (CIP) from an aqueous solution by natural zeolite, the calcium-rich clinoptilolite (CLI), and magnetite-coated CLI (MAG-CLI) was investigated. Both CLI and MAG-CLI showed a high adsorption affinity towards CIP at 283, 288 and 293 K at a pH of 5. Adsorption kinetics studied for the initial concentrations of 15-75 mg CIP dm(-3) follow Lagergren's pseudo-second order equation and the adsorption is best represented by the Langmuir model. The adsorption mechanism involves strong electrostatic interactions between negatively charged aluminosilicate lattice and the cationic form of CIP accompanied by an ion-exchange reaction. Magnetite coverage (approx. 12 wt.%) induces magnetism, which can facilitate the separation process. The coverage does not influence the adsorption activity of CLI. The leaching test showed that the MAG coating protects the adsorbent from CIP leaching. This is ascribed to interactions between the CIP carboxyl groups and magnetite nano-particles. Antibacterial tests showed strong antibacterial activity of the ciprofloxacin-containing adsorbents towards pathogenic E. coli and S. aureus.

AB  - Natural zeolite – clinoptilolite (CLI) from Serbian deposit Slanci (near the capital city Belgrade) was
investigated as adsorbent for the adsorption of antibiotic ciprofloxacin (CIP) as a model organic micropollutant (OMP) present in wastewater. At 20 °C the adsorption capacity varies from 4.81 to 8.90 mg g-1 for the initial CIP solution concentration of 15 and 50 mg CIP dm–3, respectively. The adsorption isotherms at 10, 15 and 20 °C are best represented by the Langmuir model and the adsorption kinetics by the Lagergren's pseudosecond-order equation. The adsorption mechanism most probably involves an ion-exchange reaction occurred at the CLI surface and according to results of Weber-Morris model does not involve intra-particle diffusion.

AB  - Due to their adsorbent, ion exchange and catalytic properties zeolites are suitable for a variety of applications. We report on the photocatalytic activity of a readily available and inexpensive natural zeolite clinoptilolite (Z) containing SnO2 (Sn-Z). The Sn-Z samples with 3-15 wt. % of Sn were prepared by using a precipitation-deposition method. Powder X-ray diffraction analysis showed that the zeolite structure was unaffected by the introduction of the Sn-phase. Diffuse reflectance UV/VIS spectra of the Sn-Z samples confirmed the presence of SnO2 and X-Ray absorption spectroscopy analyses suggested that the SnO2 particles mainly resided on the surface of the clinoptilolite, while ATR-FTIR analysis gave some clues that part of the SnO2 phase was incorporated in the pores of the zeolite. The presence of SnO2 in Sn-Z increased both adsorption capacity and photocatalytic performance which could be partially explained by higher surface area and partially with an increased negative potential of the surface. Adsorption and total degradation of methylene blue (MB) for the Sn-Z with the highest amount of Sn (15 wt.%) was about 30% and 45%, respectively, suggesting a synergetic effect between SnO2 and the clinoptilolite lattice. Reusability tests showed that these catalysts present a promising material for water purification.

The presence of SnO2 in Sn-Z increased both adsorption capacity and photocatalytic performance which could be partially explained by higher surface area and partially with an increased negative potential of the surface. Adsorption and total degradation of methylene blue (MB) for the Sn-Z with the highest amount of Sn (15 wt.%) was about 30% and 45%, respectively, suggesting a synergetic effect between SnO2 and the clinoptilolite lattice. Reusability tests showed that these catalysts present a promising material for water purification.",

AB  - Due to the development of resistance to antimicrobial agents, bacterium Acinetobacter baumannii is nowadays a leading cause of nosocomial outbreaks. Clinically relevant A. baumannii outside hospital settings including natural soils affected by human waste represents a public-health risk for humans and animals. The aim of this study was to investigate the potential of metal-loaded zeolites to eliminate viable A. baumannii from artificially contaminated natural soils. A. baumannii isolate was subjected to the activity of natural zeolitised tuff (NZ) and Cu-modified (CuNZ) or Ag-modified zeolite (AgNZ) in wet, slightly acidic terra rossa and slightly alkaline red palaeosol. A. baumannii survived in terra rossa and red palaeosol supplemented with 1 wt% of NZ for seven days and four months, respectively. The addition of 1 wt% of CuNZ to terra rossa and red palaeosol shortened the survival of A. baumannii to three and 14 days, respectively. The addition of 0.1 wt% of AgNZ to both soils resulted in complete removal of viable A. baumannii within 1 h of contact, while the total native heterotrophic bacterial counts remained high. Since AgNZ is prepared with a simple modification of cost-effective and environmentally friendly natural zeolite, it is a promising material for the remediation of soils contaminated with pandrug-resistant A. baumannii.

AB  - The use of natural zeolite - clinoptilolite, to protect wheat grain from storage insects within environmentally-friendly storage techniques can lead to the presence of small amounts of zeolite residues in flour. This study investigated the influence of as-received zeolite clinoptilolite (Z) and sodium-rich clinoptilolite (NaZ) in wheat dough on the dough rheological properties. Zeolites were added to dough at 0.5-1.5 wt% flour basis level, which is a range expected to remain in the grain (flour) after treatment to control storage pests. The effects were studied in two types of wheat, conventional (Triticum aestivum) and spelt (T aestivum spp. spelta) because they initially differ in rheological properties. NaZ was used to discern whether the presence of increased concentration of Na+ in the zeolite was able to exert a higher strengthening effect as compared to as-received zeolite (Z). NaZ exerted the highest dough strengthening effect which was mainly reflected as decreased dough softening and increased water absorption. The fact that the presence of NaZ was the most effective factor in improving the dough rheological profile suggested that the presence of movable cations in the zeolite lattice might have a pronounced role in the mechanism by which zeolite affects dough behaviour.

AB  - Due to structural complexity and toxicity of organic dyes their presence in water body
causes usually serious environmental problems. Advanced Oxidation Processes (AOPs) have
been recognized as effective methods for a complete degradation of organic dyes. In this
study, Serbian natural zeolite (clinoptilolite) loaded with Fe(III) was used for the preparation
of a photocatalyst and its catalytic activity was tested in the photodegradation of methylene
blue (MB) as a model cationic dye under visible light at room temperature and atmospheric
pressure. It is showed that the prepared Fe(III)-containing clinoptilolite (FeZ) can be used as
active and recyclable photocatalyst in degradation of MB.

AB  - Catalysts based on natural zeolite - clinoptilolite loaded with either SnO2 (TOHCLI) or sulfated SnO2 (STOHCLI) were prepared and tested in the esterification of levulinic acid (LA) with octanol or ethanol. The Sn content in TOHCLI and STOHCLI varied from 4.5 to 12.3 wt.%. The catalysts were characterized by powder X-ray diffraction method, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy, thermal analysis, X-ray photoelectron spectroscopy, NZ physisorption at - 196 degrees C, (27)A1 and Si-29 MAS NMR solid state spectroscopy and FTIR spectroscopy for analysis of acidic centers. A high conversion rate of LA into octyl- (OLA) or ethyl levulinate (ELA) was obtained for both TOHCLI and STOHCLI. TOHCLI showed a high activity in the conversion of LA into OLA (55%) and a moderate activity in the conversion to ELA (22%). STOHCLI led to a total conversion of LA to OLA and ELA due to the presence of a high amount of Bronsted and Lewis acid sites in the catalysts. The catalytic activity decreased to 86% for OLA and to 66% for ELA after next five cycles. Lower catalytic activity in the repeated cycles during ELA formation was explained by pore blockage due to coke formation.

A high conversion rate of LA into octyl- (OLA) or ethyl levulinate (ELA) was obtained for both TOHCLI and STOHCLI. TOHCLI showed a high activity in the conversion of LA into OLA (55%) and a moderate activity in the conversion to ELA (22%). STOHCLI led to a total conversion of LA to OLA and ELA due to the presence of a high amount of Brønsted and Lewis acid sites in the catalysts. The catalytic activity decreased to 86% for OLA and to 66% for ELA after next five cycles. Lower catalytic activity in the repeated cycles during ELA formation was explained by pore blockage due to coke formation.

AB  - Antibacterial activity of a natural zeolite, clinoptilolite (Z), enriched with about 0.4-0.5 mmol of Ag (Ag-Z), Cu (Cu-Z) or Zn (Zn-Z) was tested toward two strains of Gram-negative bacteria - Escherichia coli and Acinetobacter baumannii - in natural seawater from Adriatic Sea (Croatia). The Ag-Z and Cu-Z exhibited bactericidal activity toward E. coli and A. baumannii after 3 and 6 h of exposure, respectively. The Zn-Z showed antibacterial activity toward both strains, but lacking the bactericidal effect even after 24 h of exposure. All studied samples released metal cations in seawater. Concentration of Ag and Zn leached from Ag-Z and Zn-Z was higher than maximum allowable concentrations (MAC) for drinking water, whereas concentration of Cu was below MAC. Due to high concentration of Na+ in seawater (about 1.2 g Na+ dm(-3)) an ion-exchange process can be responsible for the leaching of the studied cations. The lowest extent of leaching from Cu-Z was ascribed to different position and geometry of sites occupied by Cu(II) in the clinoptilolite lattice. The antibacterial activity of M-Z was attributed to the metal cations leached from the zeolite lattice into seawater. The obtained results indicate that Cu-Z can be considered as a promising disinfectant for treatment of seawater.

AB  - In this study we prepared adsorbents on the basis of clinoptilolite-rich zeolitic tuff (Slanci deposit, Beograd), and chitosan, as well as partially cross-linked chitosan by glutaraldehyde. We investigated removal rate of nickel and zinc ions from the aqueous solution by both adsorbents at 25 °C, adsorption isotherms, adsorption kinetics, regeneration of spent adsorbents and their antibacterial activity. Removal rate of both adsorbents for both studied cations was significantly increased in comparison to unmodified clinoptilolite. The adsorption isotherm for Ni (II) followed the Langmuir model, while isotherm for Zn was in accord with the the Freundlich equation. Adsorption kinetics followed the Lagergren pseudo-second order kinetic model for both adsorbents and cations. The adsorbents can be regenerated to a large extent after use. Unlike unmodified clinoptilolite-based adsorbents, spent adsorbents did not show antibacterial activity. This was ascribed to interactions between chitosan coating and clinoptilolite.

AB  - Clinoptilolite is the most abundant natural zeolite in Serbia, and the Zlatokop deposit (near Vranjska Banja) is the largest deposit. The zeolitic tuff (CT) from Zlatokop contains >70 wt. % clinoptilolite with quartz and feldspar as major mineral impurities. Considering the high clinoptilolite content in the CT, this tuff has been studied in detail as an adsorbent, catalyst carrier and antimicrobial agent.  We evaluated the cation-exchange capacity for several toxic metal cations, the sorption efficiency for several anions, the catalytic activity in the processes of valorization of biomass, and the antimicrobial activity of the CT.

AB  - Several NiO contained-zeolites (NiO/H-ZSM-5, NiO/H-BETA and NiO/H-Y) prepared by a mechanochemical dry milling (MCDM) were tested in the pyrolysis of two hardwood lignins: Eucalyptus (EUC) and a mixture of birch and aspen woods (BA). All prepared catalysts increased the yield of aromatics and decreased the yield of oxygenates as compared to non-catalytic experiment. The catalytic activity depends on the lignin type and zeolite structural features. The highest liquid and gas yields and lowest coke yield was obtained with NiO/H-Y which also increased the amounts of desirable and decreased undesirable pyrolysis products, giving a high concentration of hydrogen in the gaseous phase. The highest yield of aromatics and the lowest yield of oxygenates was obtained with NiO/H-ZSM-5. The obtained results showed that BA is a more suitable feedstock, producing higher yields of liquids and aromatics and lower yields of coke and oxygenates.

AB  - The present study was aimed at examining the ability of the natural zeolitic tuff from the Zlatokop deposit in Serbia to remove Pb(II) ions from aqueous solutions under various conditions. It has been found that the adsorption proceeds via an ion-exchange reaction in which the Na+ ions from the clinoptilolite phase of the tuff are replaced to a high degree by aqueous Pb(II) ions. The removal capacity of the clinoptilolite at 298 K varies from 78 mg Pb g(-1) (for C-0 = 100 mg Pb dm-3) to 92.5 mg Pb g(-1) (for C-0 = 400 mg Pb dm(-3)), the capacity markedly increasing with temperature. The adsorption isotherm is in accord with the Langmuir model. The ion-exchange kinetics can be best described by the pseudo-second-order model. Intra-particle diffusion of Pb2+ is present in the process, but it is not the rate-limiting step and that can be explained by a modification of the Pb(II) hydration sphere during the ion-exchange. From the adsorption of Pb(II) on the studied zeolitic tuff, it is revealed that the ion-exchange process is spontaneous and endothermic, and that the standard free energy decreases with temperature.

abstract = "The present study was aimed at examining the ability of the natural zeolitic tuff from the Zlatokop deposit in Serbia to remove Pb(II) ions from aqueous solutions under various conditions. It has been found that the adsorption proceeds via an ion-exchange reaction in which the Na+ ions from the clinoptilolite phase of the tuff are replaced to a high degree by aqueous Pb(II) ions. The removal capacity of the clinoptilolite at 298 K varies from 78 mg Pb g(-1) (for C-0 = 100 mg Pb dm-3) to 92.5 mg Pb g(-1) (for C-0 = 400 mg Pb dm(-3)), the capacity markedly increasing with temperature. The adsorption isotherm is in accord with the Langmuir model. The ion-exchange kinetics can be best described by the pseudo-second-order model. Intra-particle diffusion of Pb2+ is present in the process, but it is not the rate-limiting step and that can be explained by a modification of the Pb(II) hydration sphere during the ion-exchange. From the adsorption of Pb(II) on the studied zeolitic tuff, it is revealed that the ion-exchange process is spontaneous and endothermic, and that the standard free energy decreases with temperature.",
