Metal adsorbent containing hydroxamic acid groups was successfully synthesized by radiation-induced graft copolymerization of methylacrylate onto cassava starch. The optimum conditions for grafting were studied in terms of % degree of grafting (Dg). Conversion of the ester groups present in poly(methyl acrylate)-grafted-cassava starch copolymer into hydroxamic acid was carried out by treatment with hydroxylamine in the presence of alkaline solution. The adsorbent of 191%Dg had total adsorption capacities of 2.6, 1.5, 1.4, 1.2 and 1.6 mmol/g-adsorbent for Cd $^{2+}$ , Al $^{3+}$ , UO $_2^{2+}$ , V $^{5+}$ , and Pb $^{2+}$ , respectively, in the batch mode adsorption.
