Abstract

Hydrogels, composed of poly(acrylamide-potassium methacrylate), cross-linked with N,N'-methylene bis-acrylamide, and having different proportions of poly(ethylene glycol) were synthesized by a free radical copolymerization technique. The effect of the cross-linkage and poly(ethylene glycol) contents on swelling in water, diffusion kinetics of water in the hydrogel matrix, stimuli response to pH, ionic strength of the external solution, and capacity for chromium(III) and uranyl ions from polluted water samples were evaluated. The results show that the swelling in water decreased. Still, the diffusion rate of water in the copolymer matrix increased with an increase in the cross-linkage and an increase in the poly(ethylene glycol) amount under the conditions of this study. Poly(ethylene glycol) addition provided another tool to adjust the swelling, diffusion kinetics, and adsorption characteristics of the hydrogel. For example, poly(ethylene glycol) addition made the hydrogel adsorb uranyl ions from polluted water.


Keywords: free radical polymerization, diffusion coefficient, chromium(III), uranyl ion.
