【Abstract】 In this paper, we report the graft copolymerization of acrylamide onto corn starch by Fe（Ⅱ）/H₂O₂ initiation. The IR spectra of reaction product present absorptions at 1650cm^-1, 750cm^-1, and 570cm^-1. Though the comparison from curves 1,2 and 3 the reaction product is starch-graft-poly （acrylamide）. Our results showed that the percent grafting （G） and grafting efficiency were considerably affected by [Fe²⁺],[H₂O₂], temperature, monomers and time.We found that the S-G-PAM can be useb as flocculant to treat petroliferous waste water and satisfactory result was obtained.更多还原
