Abstract: In this study, 2 types of GMA based copolymers, poly(GMA-co-HEMA-co- DVB) or PGMA and poly(VBC-co-HEMA-co-DVB)-g-GMA or PVBC-g-GMA, were prepared by suspension polymerization. Porous structures of the beads were generated by including different amounts and types of porogens in the polymerization mixture. The copolymer beads were modified by ring opening reaction of pendant epoxy groups with ethylene diamine (EDA), diethylene triamine (DETA) or tetraethylene pentamine (TEPA). The amine-functionalized beads were used for adsorption of heavy metal ions in aqueous solutions. The beads were characterized by sieve analysis, swelling study, scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FT-IR). The influences of pH, adsorption time, initial metal ion concentration, volume of metal ion solution, amine chelating agents and porogens on the adsorption capacity of the beads were investigated. The maximum adsorption capacities of (PVBC-g-GMA)-EDA beads were 2.31, 1.31, 0.93 and 0.61 mmol/g for Cu(II), Ni(II), Mn(II) and Cd(II) ions in single metal ion solutions, respectively. Comparing with (PVBC-g-GMA)-EDA, the PGMA-EDA beads were less efficient. Their adsorption capacities were 1.89, 1.14, 0.86 and 0.53 mmol/g for Cu(II), Ni(II), Mn(II) and Cd(II) ions in single metal ion solutions, respectively. It was found that these beads can be effectively used for heavy metal removal from aqueous solutions with repeatedly adsorption-desorption operations.
