AB  - In the proposed study, agro-waste biomass oat straw (OS) was considered a potential adsorbent for Cu(II), Zn(II), and Se(IV) removal from aqueous solutions. In order to obtain material with better adsorption abilities, the OS was modified by a deep eutectic solvent (DES). Structural changes caused by the applied modification route were considered by pHpzc, SEM, FTIR, and DSC/TG analysis. These methods discovered that lignocellulosic biomass degradation and material functionalization were achieved by DES treatment. Preliminary adsorption tests showed an over fourfold increase in capacity upon modification. The kinetic parameters implied that adsorption on modified material followed the pseudo-second-order kinetic model. Different isotherm models were applied to experimental data, while the Sips isotherm model best describes the equilibrium of the adsorption process on the tested modified material. According to this isotherm model, the maximum achieved adsorption capacities of Cu(II), Zn(II), and Se(IV) were 48.21, 55.06, and 87.85 mg/g, respectively. The summarized experimental results revealed that the adsorption process of selected cations on modified OS was predominantly caused by chemisorption, while, in addition to chemisorption, electrostatic forces were also responsible for Se(IV) removal. Desorption test showed that the prepared material could be reused for at least 3 cycles, with minimal efficiency loss. Briefly, this study reinforces that DES-modified agro-waste biomass could be used as a promising adsorbent for cations and oxyanions from wastewater.

AB  - A calcium-pyro-hydrochar (Ca-PHC) can be distinguished as a novel sorbent of Pb2+ and Cd2+ from an aqueous solution. It was obtained using hydrothermal treatment of the spent mushroom substrate (SMS), followed by a CaCl2·5H2O activation and pyrolysis. The characterisation of chars before and after modifications was done by scanning electron microscope (SEM), Brunauer–Emmett–Teller (BET) and Fourier transform infrared (FTIR). Batch experiments were performed to examine Ca-PHC’s sorption properties and binding mechanisms to selected metal ions. The maximum sorption capacities of Ca-PHC for Pb2+ and Cd2+ were 297 mg g−1, and 131 mg g−1, respectively. The obtained results demonstrated that the sorption of Pb2+ and Cd2+ by Ca-PHC follows a pseudo-second kinetic model and Freundlich isotherm. The binding of the selected metals onto Ca-PHC was enabled by the ion-exchange mechanism, surface complexation, mineral precipitation and cation–π interaction. Thermodynamic parameters indicate that metal ions binding by Ca-PHC are spontaneous and endothermic. Due to the high adsorption capacities, the obtained Ca-PHC has good potential for application in industrial wastewater treatment. In addition, the demonstrated use of SMS highlights another possibility of applying this specific biomass relevant to sustainable and economical waste management in the growing mushroom industry.

AB  - Silanization of the natural and synthetic zeolites as well as their use as adsorbents for removing arsenic(III) oxyanions from wastewater are the topic of this paper. Two types of zeolite were used: natural zeolite-clinoptilolite from Zlatokop deposit, Vranjska Banja, Serbia, previously converted to H+-form and synthetic zeolite, mordenite. The modification was performed with solution (3-aminopropyl) triethoxysilane (APTES). The presence of APTES on the surface of zeolite was confirmed using TG/DSC and FTIR analysis. The results showed that natural aminosilane-modified zeolite has a higher adsorption capacity for arsenic(III) oxyanions compared to mordenite prepared in the same way. The kinetic data follow the Lagergren pseudo-second-order model. This model implies a chemical interaction between AsO33–- ions and functional groups on the silanized zeolite surface.

AB  - Cancer cell immobilization in polymer hydrogels serving as extracellular matrices and cultivation in perfusion bioreactors
that provide appropriate chemical signals, efficient mass transfer and hydrodynamic shear stresses is a promising strategy
for development of physiologically relevant tumor models. In this work, perfusion cultures of 2 cancer cell types (C6 rat
glioma and embryonal carcinoma NT2/D1 cells) immobilized in alginate microgels were established, while static cultures
served as controls. Continuous perfusion had different effects on the cultured cells inducing enhanced proliferation of the
glioma cells immobilized in microfibers (8x10^6 cell/ml), while reducing the viability of the NT2/D1 cells immobilized in
microbeads (1x10^6 cell/ml). In order to elucidate the observed effects, chemical engineering principles were applied to
assess mass transfer and hydrodynamic conditions. The second Fick’s law was solved analytically while the diffusionadvection-reaction equation was solved numerically to model mass transport in the static and bioreactor cultures,
respectively. Moreover, Reynolds numbers, pressure drops and shear stresses in bioreactor cultures were calculated for
assessment of flow regime and hydrodynamic conditions. The modeling results have indicated that oxygen transport is
diffusion-controlled through the alginate hydrogel, while medium perfusion improves mass transfer of larger compounds
having smaller diffusion coefficients (∼10^(-13) m^2/s), which possibly stimulated glioma cell proliferation. On the other
hand, the obtained shear stress (~50 mPa) in the perfused packed bed of microbeads was above physiological levels, which
provided the explanation of the poor NT2/D1 cell survival. This study stresses the importance of multidisciplinary approach
in addressing such multifactorial diseases as cancer.

AB  - Fluoride ions are increasingly present in the groundwater mainly due to the anthropogenic activity. On the other hand, increased awareness of harmful effects caused by high concentrations of F-in drinking water, leads to severe standards of water quality. Because of this, intensive researches of new methods for fluoride removal from water streams have been made in last decade. This paper examines the potential of aluminum alginate particles as a cheap and efficient biosorbent for F- removal. The adsorbent characterization before and after F- adsorption was performed using FT-IR technique.

AB  - In this study the novel biosorbent - raw corn silk (CS) was investigated for Cu2+ and Zn2+ removal from aqueous solutions. The physical and chemical properties of CS were determined by SEM - EDX and ATR - FTIR techniques. The SEM micrographs revealed that surface morphology of CS is suitable for metal adsorption, while FTIR analysis confirmed presence of various active groups (O-H, C-O, C-O C, C=C and amide II) which could interact with metal ions. The adsorption experiments were performed in batch system. Experimental data were fitted by pseudo - first order and pseudo - second order kinetic models as well as Langmuir and Freundlich isotherm models. Biosorption of the both metals follow pseudo second order kinetic model. The best fitting adsorption model is Langmuir model and the maximum biosorption capacities (q(max)) for Cu2+ and Zn2+ at 313 K and pH 5.0 were 15.35 mg g(-1) and 13.98 mg g(-1), respectively. The thermodynamic parameters such as Gibbs free energy change (Delta G), enthalpy change (Delta H) and entropy change (Delta S) were studied at different metal concentration and three temperatures. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. According to thermodynamic study, the biosorption process for both metals is feasible, endothermic and spontaneous. Ion - exchange is the dominant mechanism in adsorption of Cu2+ and Zn2+ on the CS with a certain degree of complexation. Desorption study was performed in three adsorption/desorption cycles with diluted nitric acid. Results show that after metal adsorption CS can be efficiently recovered and reused for new adsorption process. Obtained results indicated that corn silk could be used as efficient novel biosorbent for Cu2+ and Zn2+ removal from water samples.

Results show that after metal adsorption CS can be efficiently recovered and reused for new adsorption process. Obtained results indicated that corn silk could be used as efficient novel biosorbent for Cu2+ and Zn2+ removal from water samples.",

AB  - The objective of this study was to investigate corncob as biosorbent for heavy metals removal from aqueous solutions. All biosorption experiments were performed in batch system. The biosorbent were caracterized by thermal analysis (DTA/TGA), Scanning Electron Microscopy and Energy Disperzive X-Ray analysis (SEM-EDX) and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis of corn cob before and after Pb2+, Cu2+ and Zn2+ removal from aqueous solutions showed that ion exchange and chemisorption were involved in biosorption process of metal ions on to corn cob. Experimental data were fitted by Langmuir and Freundlich isotherm models. Maximum adsorption capacity of corn cob for Pb2+, Cu2+ and Zn2+ were 5,59; 2,62 i 1,23 mg/g, respectively. Desorption study showed that metal adsorbed corn cob can be effectively regenerated by HNO3 solution. Results from this study indicated that corn cob can be used as potential biosorbent for Pb2+, Cu2+ and Zn2+ removal from aqueous solutions.
AB  - Cilj ovog rada je ispitivanje mogućnosti upotrebe oklaska kukuruza za uklanjanje teških metala iz vodenih rastvora. Svi biosorpcioni eksperimenti izvođeni su u šaržnom sistemu. Karakterizacija biosorbenta izvršena je termijskom analizom (DTA/TGA), metodom skenirajuće elektronske mikro-skopije i energijsko-disperzivne rendgenske analize (SEM-EDX) i infracrvenom spektroskopijom sa Furijeovom transformacijom (FTIR). Na osnovu FTIR analize oklaska kukuruza pre i nakon uklanjanja Pb2+, Cu2+ i Zn2+ jona, ustanovljeno je da jonska izmena i hemisorpcija učestvuju u procesu biosorpcije jona metala na oklasku kukuruza. Eksperimentalni rezultati obrađeni su Lengmirovim i Frojndlihovim modelom izotermi. Maksimalni adsorpcioni kapacitet oklaska kukuruza za Pb2+, Cu2+ i Zn2+ iznosi 5,59; 2,62 i 1,23 mg/g, respektivno. Nakon ispitivanja procesa desorpcije zaključeno je da se adsorbovani joni metala na oklasku kukuruza efikasno i lako mogu ukloniti rastvorom HNO3. Rezultati ovog istraživanja ukazuju da se oklasak kukuruza može primeniti kao potencijalni biosorbent za uklanjanje Pb2+, Cu2+ i Zn2+ jona iz vodenih rastvora.

AB  - In this study, carbonization products of grape pomace (hydrochar and process water) have been thoroughly characterized in order to assess its fuel properties, physico-chemical composition and to optimize its production. The obtained detailed insight into transformations of the biomass during hydrothermal conversion between 180-220 degrees C revealed that the hydrochar obtained at 220 degrees C exhibits a considerable energetic potential, increased porosity and re-adsorption abbility. Hydrothermally induced structural changes in the obtained hydrochars were unveiled by thermal and morphology analysis, FTIR and NIR spectroscopy. Temperature increment caused a decrease in antioxidative capacity, anthocyanin and organic acid content in process water and simultaneous increase in total phenolic and individual organic components content. The overall effect of the reaction temperature on products characteristics was assessed by multivariate data analysis. Obtained results substantiated the suitability of hydrothermal conversion of grape pomace into highly valuable fuels and versatile products.
