Özet

Details of the adsorption performance of poly(2-hydroxyethylmethacrylate-methacrylamidocysteine) [p(HEMA-MAC)] beads towards the removal of heavy metal ions from aqueous solution were studied. The metal-complexing ligand and/or co-monomer MAC was newly synthesized from methylacrylochloride and cysteine. Spherical beads of average size 150-200 mum were obtained by the radical suspension polymerization of MAC and HEMA conducted in an aqueous dispersion. The p(HEMA-MAC) beads obtained had a specific surface area of 18.9 m(2)/g.
