Graft copolymerization of acrylamide monomer onto cellulose, using ceric ammonium nitrate as initiator, was investigated. Water and metal ions sorption by this grafted cellulose were estimated. The conditions of grafting, e.g. grafting time, dose of initiator, ratio of monomer to cellulose, acid concentration and liquor ratio, were evaluated. The different properties as graft and graft efficiency percentage, as well as polymerization percent, have been determined. Grafted cellulose has been characterized by FTIR and swelling studies. Sorption of different metal ions in the mixture, e.g. Cu, Cr, Ni, and Pb, by grafted cellulose was investigated. The effect of hydrolysis of grafted cellulose by using sodium hydroxide on its swelling properties and metal ions sorption was also investigated. Hydrolysis increases the sorption affinity of grafted cellulose toward water and metal ions . |
