Macroporous glycidyl methacrylate-divinylbenzene copolymer resins were synthesized by suspension polymerization using toluene-n-heptane mixture as a porogen

and their aminated resins were prepared by the reaction of epoxy groups in the copolymer resins with polyethylene polyamines. The measurements of exchange capacity

pore volume and porosity showed that amino content

pore volume and porosity of the aminated resins decreased as the contents of divinylbenzene increased

and that pore volume and porosity of the aminated resins increased with increasing amount of the porogen. The results of the adsorption of Cu2+

Co2+

Ni2+ and Zn2+ on the aminated resins showed that the aminated resins had good adsorption capability of the four ions and the adsorption amount of Cu2+ was much higher than those of the other three ions. The adsorption rates of the four metal ions on the aminated resins depended on amination with polyethylene polyamines and the contents of divinylbenzene and the porogen. The adsorption kinetics can be described by pseudo second-order rate equation.
