A modified suspension polymerization was used for the preparation of the mesoporous magnetic-poly(divinylbenzene-co-vinylimidazole) (m-poly(DVB-VIM)) microbeads in size 53-212 μm of average diameter. The specific surface area and the DVB/VIM mol ratio of the microspheres were determined as 29.47 m2/g and 1:4 mol/mol with Fe3O4, respectively. The physicochemical studies of adsorption of Ni(II) ions from aqueous solutions such as pH, initial concentration, amount of mesoporous m-poly(DVB-VIM) microbeads, contact time, and temperature onto the m-poly(DVBVIM) microspheres were carried out. The maximum adsorption capacities of the m-poly(DVB-VIM) microspheres towards Ni(II) ions were determined as 13.51, 20.14, 21.00 and 23.62 mg/g at 277 K, 298 K, 318 K, and 338 K, respectively. The dynamic and equilibrium adsorption behaviours of the system were adequately described by the pseudo-second-order kinetic and the Langmuir isotherm models, respectively. Various thermodynamic parameters, such as the Gibbs' free energy change ( Δ Go), the standard enthalpy change (Δ Ho) and the standard entropy change (Δ So) were also determined. Morever, after use in the adsorption, the m-poly(DVB-VIM) microbeads with paramagnetic property was separated from the via the applied magnetic force. These results indicate that the material studied could be used as a purifier for the removal of Ni(II) ions from water and wastewater under magnetic field.
