Preparation of the Copolymer of Acrylic Acid and Acrylamide Grafted onto Polyethylene and its Complexation with Samarium Ion

Abstract

Acrylic acid (AA) and acrylamide (AAm) were graft-copolymerized onto polyethylnene (PE) powder by the preirradiation method. Complex formation constants of Sm ion with the PE powder 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 γ-ray irradiation on PE-g- (AA-co-AAm) and PE-g-AA, the adsorption did not decrease.
