AB  - Introduction/purpose: In this study, we investigated the possibility of removing the organophosphorus pesticide malathion from water using a new adsorbent based on the biowaste of river shell shards from the Anodonta Sinadonta woodiane family, a material that accumulates in large quantities as waste on the banks of large rivers. Two adsorbents were tested - mechanically comminuted river shells (MRM) and mechanosynthetic hydroxyapatite from comminuted river shells (RMHAp). Methods: The obtained adsorbents were characterized and tested for the removal of the organophosphorus pesticide malathion from water. In order to predict the optimal adsorption conditions using the Response Surface Method (RSM), the authors investigated the influence of variable factors (adsorption conditions), pH values, adsorbent doses, contact times, and temperatures on the adsorbent capacity. Results: The best adsorption of malathion was achieved at mean pH values between 6.0 and 7.0. The adsorption data for malathion at 25, 35, and 45 °C were compared using the Langmuir, Freundlich, DubininRadushkevich (DR), and Temkin isothermal models, as well as pseudofirst order, pseudo-second order and Elovic kinetic models for modeling adsorption kinetics. The maximum Langmuir adsorption capacity for MRM and RMHAp at 25 °C was 46,462 mg g-1 and 78,311 mg g-1 , respectively. Conclusion: The results have showed that malathion adsorption on both adsorbents follows the pseudo-second kinetic model and the Freundlich isothermal model. The thermodynamic parameters indicate the endothermic, feasible, and spontaneous nature of the adsorption process.

AB  - The synthesis and adsorption potential of Cy-npAg, obtained by modification of raw montmorillonite clay (raw-Cy) with silver nanoparticle (npAg), was studied in this work. Optimization procedure, with respect to time, temperature and amount of deposit npAg, obtained either by reductive precipitation or ultraviolet irradiation, was performed using response surface methodology (RSM). The most efficient adsorbent, obtained by chemical reduction of silver ion with sodium borohydride, named Cy-npAg, was characterized in detail using Brunauer-Emmett-Teller, scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction techniques, and point of zero charge determination. The Cy-npAg showed good adsorption capacity with respect to non-systemic organophosphate insecticide (diazinon) as well as of heavy metals ions (Cd2+ and Ni2+ ions), that is, 74.26, 62.33, and 35.49 mg g(-1), respectively, obtained from Langmuir model fitting. Temperature dependent kinetic study allowed determination of pseudo-second rate constant (10(3) g mg(-1) min(-1))/activation energies (kJ mol(-1)): 1.45/14.48 for diazinon, and 1.27/6.59 and 0.7/7.35 kJ mol(-1) for Cd2+ and Ni2+ ions, respectively. Thermodynamic parameters indicated feasible and spontaneous adsorption with main participation of physisorption. Antibacterial potential of npAg deposit for water disinfection was confirmed by the moderate reduction of bacterial growth of Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa, by 64%, 39%, and 70%, respectively. Thus, two synergistic effects contribute to water purification processes using Cy-npAg: pollutants removal with a simultaneous decrease of the microbial contamination contributing to overall water quality improvement.

AB  - This batch and column kinetics study of arsenic removal utilized copper-impregnated natural mineral tufa (T-Cu(A-C)) under three ranges of particle size. Non-competitive kinetic data fitted by the Weber-Morris model and the single resistance mass transfer model, i.e., mass transfer coefficient k(f)a and diffusion coefficient (D-eff) determination, defined intra-particle diffusion as the dominating rate controlling step. Kinetic activation parameters, derived from pseudo-second-order rate constants, showed low dependence on adsorbent geometry/morphology and porosity, while the diffusivity of the pores was significant to removal efficacy. The results of competitive arsenic adsorption in a multi-component system of phosphate, chromate, or silicate showed effective arsenic removal using T-Cu adsorbents. The high adsorption rate-pseudo-second-order constants in the range 0.509-0.789gmg(-1)min(-1) for As(V) and 0.304-0.532gmg(1)min(1) for As(III)-justified further application T-Cu(A-C) in a flow system. The fixed-bed column adsorption data was fitted using empirical Bohart-Adams, Yoon-Nelson, Thomas, and dose-response models to indicate capacities and breakthrough time dependence on arsenic influent concentration and the flow rate. Pore surface diffusion modeling (PSDM), following bed-column testing, further determined adsorbent capacities and mass transport under applied hydraulic loading rates.

AB  - Synthesis of branched aminated waste polyacrylonitrile (PAN) fibers, realized in a three addition/amidation successive steps, was performed in order to obtain AS3-PAN adsorbent. Influence of various operating parameters such as pH, contact time, adsorbent mass and initial concentration of pollutants, on adsorption capacity has been studied. Design of the experimental plan of adsorption experiments, defined by response surface methodology (RSM), rationalized the number of necessary experiments. The calculated adsorption capacities for AS3-PAN, obtained by Langmuir model, were 58.94, 41.07, 34.51, 24.54 and 29.61 mg g(-1) for Pb2+, Cd2+, Ni2+, Cr(VI) and As(V) ion, respectively. The results of pseudo-second-order reaction rate and Weber-Morris kinetic model indicated significant resistance due to intra-particle (pore) diffusion. The experimental results were compared with the theoretically calculated ones, obtained by RSM prediction model, and validation of applied methodology was performed by testing the quality of the regression analysis with analysis of variance test.

GAP was prepared by azidation of poly(epichlorohydrin) (PECH) with different polyol units in the polymer chain. PECH was obtained by cationic ring-opening polymerization of epichlorohydrin, with BF3-etherate as a catalyst and polyol as a co-catalyst. The synthesized polymers have been characterized using IR-spectroscopy, while the prepolymers structure was confirmed by proton NMR spectroscopy. Additionally, glass transition temperature (Tg) and sensitivity to thermal stimuli were determined.

AB  - The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these precursor materials and modified with goethite nano-deposit, alpha-FeOOH, A1/ and A2/MWCNT-alpha-FeO(OH) adsorbents used for As(V) removal. In a batch test, the influence of pH, contact time, initial ion concentration and temperature on adsorption efficiency were studied. Adsorption data modelling by the Langmuir isotherm, revealed good adsorption capacities (in mg g(-1)) of 18.8 for As(V) and 60.1 and 44.2 for Pb2+ and Cd2+ on A2/MWCNT, respectively. Also, 27.6 and 29.8 mg g(-1) of As(V) on A1/ and A2/MWCNT-alpha-FeO(OH), respectively, were removed. Thermodynamic parameters showed that the adsorption is spontaneous and endothermic processes. Results of the study of influences of competitive ions: bicarbonate, sulfate, phosphate, silicate, chromate, fluoride and natural organic matter (NOM), i.e., humic acid (HA), showed the highest effect of phosphate on the decrease of arsenate adsorption. Time-dependent adsorption was best described by pseudo-second-order kinetic model and Weber-Morris model which predicted intra-particle diffusion as a rate-controlling step. Also, activation energy (E-a/kJ mol(-1)): 8.85 for Cd2+, 9.25 for Pb2+ and 7.98 for As(V), were obtained from kinetic data.

AB  - Performance of a novel adsorbent, copper impregnated natural mineral tufa (T-Cu), applicable for efficient arsenic removal is presented in this study. Testing of adsorbent properties encompassed material characterization and equilibrium study in a batch system. Copper modification contributed to increased adsorption capacities, that is, from 4.65 to 67.83 mg g (1) for As(III), and from 6.84 to 104.62 mg g (1) for As(V), comparing to unmodified tufa. The obtained thermodynamic data indicated higher feasibility and spontaneity of the adsorption process at higher temperature. A competitive study in a multi-component system showed that T-Cu adsorbents effectively removed arsenic species at high concentrations of interfering ions. The high adsorption capacity and multi-cycle reusability gave positive techno-economic indicators in comparison to commercial adsorbents.

AB  - Unmodified farming carp (cyprinus carpio) scales were used as a biosorbent for the removal of Cd(II), Pb(II) and As(V) ions from aqueous solutions. The adsorption studies were conducted as a function of pH, contact time and temperature. The best sorption of cadmium, lead and arsenate ions was achieved for pH between 6.0 and 8.0. The adsorption data for cadmium, lead and arsenate at 20, 30 and 40 degrees C are fitted to Langmuir, Freundlich, Sips, Dubinin-Radushkevich (D-R), Jovanovic, Jovanovic-Freundlich (J-F), Temkin, Toth and Koble-Corrigan (K-C) isotherm models. Experimental data were used to model adsorption kinetics using pseudo-first order, pseudo-second order, Elovich and intraparticle diffusion kinetic models. The results showed that the adsorption of Cd(II), Pb(II) and As(V) ions onto carp scale followed the pseudo-second-order kinetic model. Thermodynamic parameters, including the Gibbs free energy (Delta G(0)), enthalpy (Delta H-0), and entropy (Delta S-0) changes, indicated that the present adsorption process was feasible, spontaneous and endothermic in the temperature range of 20-40 degrees C.

AB  - In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics of raw and modified MWCNTs were investigated in batch adsorption experiments. The influence of solution pH (pH range 3-10), contact time, and temperature (25, 35, and 45 degrees C) were studied. Ethylenediamine-functionalized MWCNTs have the greatest affinity for arsenate ions, followed by o-MWCNTs and raw-MWCNTs. The obtained experimental data for raw- and o-MWCNTs fitted Sips isotherm model, while for the e-MWCNTs, the Freundlich model provided the best fit to the experimental points. The maximum adsorption capacity for arsenate ions was achieved using e-MWCNTs, 12.18mgg(-1). The presence of the arsenate on the adsorbent is confirmed by FTIR spectroscopy. Thermodynamic studies indicated the spontaneity and endothermic nature of the adsorption. Sodium hydroxide solution (0.1M) was found to desorb about 70% of arsenate from e-MWCNTs. The results with spiked drinking water samples demonstrated that e-MWCNTs, due to the present basic and acidic groups, were very efficient for the removal of arsenate ions, as well as of some cations, at pH 4.

AB  - Multi-wall carbon nanotubes (MWCNTs) was functionalized with 6-arm amino polyethylene glycol (PEG), and synthesized PEG-MWCNTs was used as adsorbent in order to study adsorption characteristics with respect to Cd(II), Pb(II) and As(V) ions. In batch tests, the influence of contact time, initial metal ion concentration and temperature on the ion adsorption on PEG-MWCNTs was studied. Adsorption of Cd(II), Pb(II) and As(V) on PEG-MWCNTs strongly depends on pH. Time dependent adsorption can be described by intra-particular Weber-Morris kinetic model, and adsorption process was modelled by Koble-Corrigan isotherm, respectively. The maximum adsorption capacities of Cd(II), Pb(II) and As(V) on PEG-MWCNTs, for initial concentration of 10 mg dm(-3) and at pH=4, were 77.6, 47.5 and 13 mg g(-1) at 25 degrees C, respectively. The competitive adsorption studies showed that the adsorption affinity of ions towards PEG-MWCNTs showed largest adsorption of Cd(II) at pH 8, following by Pb(II) at pH 6, and As(V) at pH 4. Thermodynamic parameters showed that the adsorption of Cd(II), Pb(II) and As(V) ions was spontaneous and endothermic.
