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...
Networks based on extracted cellulose and its derivatives such as hydroxypropyl cellulose (HPC), cyanoethyl cellulose, hydroxyethyl cellulose, hydrazinodeoxy cellulose, cellulose phosphate with acrylamide (AAm) and N, N-methylene bisacrylamide synthesized by simultaneous gamma ray initiation were used for sorption of Fe 2+ , Cu 2+ and Cr 6+ ions. The effect of partial hydrolysis...
