Cross-linked copolymer beads were prepared by suspension polymerization of styrene (0.90mol) and divinyl benzene (DVB) (0.10mol) mixtures. The resulting copolymer beads with sulfonamide-based quaternary amide functions were prepared in three steps: (1) by chlorosulfonation with chlorosulfonic acid; (2) by sulfonamidation reaction with N,N-dimethylethylenediamine; and (3) by quaternization reaction with chloroacetamide. The resulting polymer resin, which had a chloroacetamide content of 2.50mmol/g, was effective in extracting mercury from aqueous solutions. The mercury sorption capacity was around 3.0mmol/g in non-buffered conditions. Experiments performed in identical conditions with several metal ions revealed that Cd(II), Mg(II), Zn(II), and Fe(III) ions also were extractable in low quantities (0.2-0.8mmol/g). The sorbed mercury could be eluted by repeated treatment with hot acetic acid without hydrolysis of the amide groups.
