摘　　要：以过硫酸钾为引发剂,N,N'-亚甲基双丙烯酰胺为交联剂,采用自由基聚合法使羧甲基纤维素与丙烯酸进行接枝共聚并掺杂聚苯胺,应用于Pb(Ⅱ)的吸附研究,考察了原料配比、pH、溶液浓度、吸附时间对吸附性能的影响。结果表明:羧甲基纤维素、丙烯酸和聚苯胺的质量比为2∶3∶1、pH=6时复合材料表现出最佳吸附性能;吸附时间为45 min时,吸附率大于97%。Grafted copolymerization of acrylic acid on carboxymethylcellulose intermingled with Polyanilineani-line, using ammonium peroxydisulfate as the intiator and N ,N＇-methylenebisacrylamide as the cross-linking agent, was prepared from carboxymethyleellulose, acrylic acid and aniline by the method of copolymerization and cross - linking, and applied to Pb（Ⅱ） absorbefaeient. The results show that the adsorption rate is more than 97%, when pH = 6, adsorbent period is 45 minutes and concentration of Pb（Ⅱ） is 100 mg/L.
