Graft Copolymerization of Acrylamide onto Psyllium and its Applications

Psyllium is among one of the most important and most studied polysaccharide. The graft copolymerization of the acrylamide onto psyllium by microwave initiated synthesis without using any initiator. The different reaction parameter such as monomer concentration, polysaccharide concentration, reaction temperature, reaction time, pH were optimized to get the maximum percent grafting. The formation of polymer were confirmed by FTIR, TGA, SEM and XRD spectroscopy. The graft copolymer successfully used for the removal of metal ion, organic dyes from aqueous system and discoloration of dye solution.
