ABSTRACT:  Macroreticular chelating resins (RCSNHs) containing amidoxime groups were prepared from chloromethylstyrene-divinylbenzene copolymer beads (RCSs). The resins (RCCSNHs) having higher density of amidoxime groups were prepared from chloromethylated RCSs. The influence of specific surface area, pore volume, pore radius and density of amidoxime groups on adsorption ability for metal ions was investigated. Adsorption ability was greatly affected by pore structure of the resins. RCCSNHs showed higher adsorption ability than the corresponding RCSNHs prepared from the same RCSs. The density of amidoxime groups in the resins affected adsorption ability for metal ions.
