AB  - Vanadium and its compounds have multiple applications in industry, such as in alloys to increase strength and as a catalyst. Vanadium(V) is the dominant form in the aquatic environment and also, it is the most hazardous product which can cause an environmental problem due to its high solubility and toxicity. The aim of this study was to investigate the possible use of a novel magnetic polymer/bentonite composite prepared by suspension copolymerization of glycidy. methacrylate (GMA) and ethylene alyco. dimethacrylate (EGDMA) and functionalize with ethylene diamine and hexamethylene diamine (MB-PSME-ED and MB-PGME-HD), for V(V) sorption from

aqueous solution. The influence of contact time on V(V) sorption onto MB-PGME-ED and MB-PGME-HD was investigated. All sorption experiments were performed in batch static conditions, at pH 7.6 and room temperature (298 K). Maximum sorption capacities, Qmax, were 2.47 mg/g and 1.94 mg/g for MB-PGME-ED and MB-PGME-HD, respectively. Surface-reaction (pseudo-first order, pseudo-second order and Elovich) and particle diffusion based (intra-particle diffusion, liquid film diffusivity model, Bangham, Boyd and McKay's) kinetic models were used for analysis of V(V) sorption kinetic data. Both sorbents obeyed the pseudo-second order kinetic model, with evident influence of pore diffusion. Desorption experiments of V(V) loaded MB-PGME-ED and MB-PGME HD performed with 0.1 M NaOH and 0.1 M HNO3 showed that NaCH is a better stripping agent for V(V) ion within both samples.
