In present research work natural bio polymer "Chitosan" was grafted onto Acrylic acid and Acrylamide and adsorption of some heavy metal studied by batch method. Synthesis of grafted chitosan supersorbent was synthesized by radical polymerization method. The adsorption of heavy metal cations, Cu(II), Cd(II), Ni(II), and Pb(II) from aqueous solution by newly-synthesized superabsorbent composite of chitosan-g-poly (acrylicacid-co-acrylamide) was investigated. The superabsorbent gel wasdoi:10.11648/j.sjac.20140206.12 fatcat:kkc4gp35gnfp7c54k7iebxpdly
