AB  - Magnetite (MG) modified cellulose membrane (Cell-MG), obtained by reaction of 3-aminosilane and subsequently with diethylenetriaminepentaacetic acid dianhydride functionalized waste Cell fibers (Cell-NH2 and Cell-DTPA, respectively), and amino-modified diatomite was used for Azoxystrobin and Iprodione removal from water. Cell-MG membrane was structurally and morphologically characterized using FT-IR and FE-SEM techniques. The influences of operational parameters, i.e. pH, contact time, temperature, and the mass of adsorbent on adsorption and kinetics were studied in a batch system. The calculated capacities of 35.32 and 30.16 mg g(-1) for Azoxystrobin and Iprodione, respectively, were obtained from non-linear Langmuir model fitting. Weber-Morris model fitting indicates the main contribution of intra-particle diffusion to overall mass transport resistance. Thermodynamic data indicate spontaneous and endothermic adsorption. The reusability of adsorbent and results from wastewater purification showed that Cell-MG could be used as general-purpose adsorbent. The adsorbent/adsorbate surface interaction was considered from the results obtained using density functional theory (DFT) and calculation of molecular electrostatic potential (MEP). Thus, a better understanding of the relation between the adsorption performances and contribution of non-specific and specific interactions to adsorption performances and design of novel adsorbent with improved properties was deduced.

AB  - Comparative adsorption study related to benefits of parent media size, i.e. microfibrillated cellulose (MC) versus nanocellulose (NC) support, for the preparation of magnetite (MG) based high performance adsorbent for arsenic removal was conducted. Precipitation of MG on amino terminal branched organic structure, L, either linked by maleic acid residue on NC surface (NC-MA/L) or linked by oxalyl bridge on MC surface (MC-O/L) produced NC-MA/L-MG and MC-O/L-MG adsorbents, respectively. Precipitation of nanosized MG on amino functionalized NC-MA/L and MC-O/L, performed according to optimized procedure, contributed to improved textural properties and adsorptive/kinetic performances of novel adsorbents. Adsorption capacity of arsenate, As(V), was in favor of NC-MA/L-MG (85.3 versus 18.5 mg g(-1)) while MC-O/L-MG exhibited faster kinetics (0.541 versus 0.189 g mg(-1) min(-1)). Lower capacity of arsenite, As(III), removal, 68.3 mg g(-1) for NC-MA/L-MG and 17.8 mg g(-1) for MC-O/L-MG, were obtained. Calculated activation energies, 13.28 and 10.87 kJ mol(-1) for NC-MA/L-MG and MC-O/L-MG with respect to As(V), respectively, suggest, in accordance with results of Weber-Morris fitting, that internal mass transfer controls adsorption process. Model free adsorption kinetics confirmed beneficial uses of MC-O/L-MG due to low activation energy dependence on the extent of adsorption.
