Abstract

The polymeric material of poly (acrylamide-acrylic acid-dimethylaminoethyl methacrylate) “PAM-AA-DMAEM” was prepared by gamma radiation-induced polymerization of dimethylaminoethyl methacrylate (DMAEM) in the presence of prepared poly(acrylamide-acrylic acid) “PAM-AA” as a template polymer using a template polymerization technique.

The effect of gamma radiation on the polymerization process showed that the conversion increases with increasing the radiation dose. The obtained polymer is water-soluble polymer at low doses <10 KGy. On increasing the radiation dose the polymer was converted into a gel with the swelling degree vary from 15–36. It was found that the capacities of the obtained polymeric gels toward Cu2+ increase with increasing the absorbed dose, monomer concentration and the template polymer/monomer molar ratio.

Spectroscopic studies showed that the mechanism of the floc formation is due to the interaction between the polymer and copper sulphate is a bond formation between the active groups of polymer chains and ions of copper sulphate. The amide and tertiary amino groups form complex with Cu2+ while carboxylic group interacts with ion through ion-exchange mechanism.
