Abstract
Acrylamide polymeric resins such as: poly(acrylamide-acrylic) acid p(AM-AA), poly (acrylamide-acrylic acid-diallylamine hydrochloride p(AM-AA-DAA)+Cl−] and poly(acrylamide-acrylic acid-diallylethylamine hydrochloride) p[(AM-AA-DAEA)+Cl−] were prepared by gamma radiation-initiated template polymerization of acrylic acid on acrylamide polymers. Copolymerization of acrylic acid with acrylonitrile produce poly(acrylic acid-acrylonitrile) p(AA-AN) resin. The capacities of the prepared polymeric materials were investigated at different doses. The results showed that the maximum experimental capacities are similar to their theoretical values. The chemical stability of the polymeric materials were investigated at different pH-values. The mechanism of interaction between the functional groups of the polymeric chains and ions in aqueous solution were studied. The polymeric materials have extraordinary capacities and were used as good exchangers in the treatment of wastewater for removal of metallic ions from their aqueous solutions.
