Chitosan was modified by gamma radiationeinduced grafting with maleic acid and then used for theremoval of cobalt ions from aqueous solutions. Chitosan-g-maleic acid was characterized by FourierTransform infrared spectroscopy (FT-IR). The effect of the dose (1e5 kGy) and monomer concentration(0.3e1.3%, m/v) on the grafting ratio was examined. The adsorption kinetics and isotherms were alsoinvestigated. The results showed that the optimal dose for grafting was 2 kGy. When monomer concentrationwas within the range of 0.3e1.3% (m/v), the grafting ratio increased almost linearly. For theadsorption of cobalt ions by chitosan-g-maleic acid beads, the pseudo second-order kinetic model(R2 ¼ 0.99) and Temkin isotherm model (R2 ¼ 0.96) were able to fit the experimental data reasonablywell. The equilibrium adsorption capacity of cobalt ions increased from 2.00 mg/g to 2.78 mg/g afterchitosan modification
