摘　　要：本文以硝酸铈铵为引发剂 ,通过接枝共聚反应 ,在淀粉骨架上引入聚丙烯酰胺 ,制得了淀粉-丙烯酰胺接枝物 ,通过对高矿化度油田废水的处理实验表明In this paper, graft copolymer of Starch-acrylamide was prepared using ceric ammonium nitrate as intiator by graft polymerization. The graft copolymer has good performance in aspect of removing turbidity and decreasing value of chemical oxyen demand (COD)when applied as flocculant for treating oilfield wastewater with high mineralization.
