Using ceric ion initiator in aqueous medium, ethyl acrylate and methacrylic acid were each grafted onto carboxyl methyl-containing holocellulosic materials obtained by treating corn cob-based holocellulosic materials with sodium hydroxide and sodium monochloroacetate. Ethyl acrylate and methacrylic acid were also grafted onto corn cob pulp. The grafted copolymers were characterized using FT-IR. The adsorption of As, Ni, and Mn metal ions were investigated using ICP-AES. The results obtained indicate that the percent ion absorbed per gram of copolymer depended on the polarity of monomer, the polarity of the holocellulose, and the initiator concentration.
