Chelating resins of crosslinked polystyrene (PS) beads have been prepared by introduction of glyoxime group by subsequent reactions of acylation, oxidation and oximation with hydroxylamine. Ethylene glycol dimethacrylate (EGD) or tetraethylene glycol diacrylate (TGD) was used in the suspension polymerization system of styrene and divinylbenzene (DVB) in order to give hydrophilicity to the beads and 2, 2, 4-trimethylpentane was used as a diluent. It has been found that porous or reticular type PS beads having large surface area is obtainable from this system and they have high capacity of adsorbing metal ions such as $UO^{2+}_2, ;Cu^{2+}, ;Ni^{2+}$dissolved in water due to their high ability of chelation of glyoxime group and enhanced hydrophilicity of the resin due to the presence of hydrophilic crosslinking agent unit. It was also recognized that the largest capacity of adsorption was exibited at pH 4~5 and a high selective adsorption to $UO^{2+}_2$.
