摘　　要：合成了聚丙烯酰胺与环糊精的接枝化合物 ,研究了该接枝化合物对模拟水样中污染物的去除能力。试验结果表明 ,β 环糊精和聚丙烯酰胺的接枝化合物与聚丙烯酰胺相比 ,对重金属离子Cu2 + 、Zn2 + 、Cd2 + 、Pb2 + 。A kind of β-cyclodextrin-polyacrylamide graft compound was synthesized.Its flocculating effect on the pollutants in simulated wastewater was studied.The results showed that on comparison with β-cyclodextrin,the graft compound has better performance for removing heavy metal ions such as Cu^(2+) ,Zn^(2+),Cd^(2+),Pb^(2+),and organic pollutants such as phenol and aniline.
