Abstract
In this study, the acrylonitrile (AN)-divinylbenzene (DVB)-methylacrylate (MA) resin was synthesized via suspension polymerization in the presence of toluene as a diluent, and benzoylperoxide (BPO) as an initiator. The effect of MA, toluene and alkaline treatment on the exchange capacity of the resin were investigated. The results showed that the anion exchange capacity decreases with an increase of the amount of MA, while alkaline treatment has no significant effect. Also, the cation exchange capacity increases with an increase in the amount of hydrophilic agent and reaches a maximum. The sorption equilibrium was achieved relatively fast within 40 minutes. The adsorption of uranium was directly depends on the pH value. Finally, the alkaline treatment enhances the potential for the much faster adsorption and the chelating resin provides a more favourable pore structure for the rapid diffusion of the ions.
