Acrylic acid (AA) and acrylamide (AAm) were graft-copolymerized onto polyethylnene (PE) powder by the pre-irradiation method. Complex formation constants of Sm ion with the PE power grafted with both AA and AAm (PE-g-(AA-co-AAm)) were larger than those with the PE powder grafted with AA (PE-g-AA). Sm ion was efficiently separated from the solution containing both Sm ion and a transition metal ion such as Cu ion. Even after the gamma -ray irradiation on PE-g-(AA-co-AAm) and PE-g-AA, the adsorption did not decrease.
