In the present article, we report two well-characterized hydrogels for the adsorption of uranyl ions from 5% NaCl solution. The hydrogel was synthesized by free radical initiation from acrylamide and acrylic acid using N,N-methylenebisacrylamide as crosslinker. In order to improve ion uptake performance, the hydrogel was hydrolyzed to partially convert some of the amide groups into carboxylate groups...
Hydrogels of two important biopolymers (dextrin and starch) with different acrylamide monomers viz., acrylamide, N-isopropyl acrylamide and 2-acrylamido-2-methylpropanesulfonic acid and crosslinked with N,N-methylene bisacrylamide were used as sorbents for three transition metal ions. These hydrogels have high water absorption capacity and also have ion exchange groups. The hydrogels have been used...
To develop low-cost and environmentally friendly polymeric materials for enrichment, separation and remediation of metal ions from water, novel reactive graft copolymers based on cellulose extracted from pine needles were synthesized by grafting of poly(glycidyl methacrylate) alone and with comonomers acrylic acid, acrylamide and acrylonitrile by benzoyl peroxide initiation. Structural aspects of...
