摘　　要： 利用化学氧化法合成了苯胺-邻氨基苯酚的共聚物,并通过静态实验研究了材料对水中汞离子的吸附性能。研究结果表明,该共聚物对废水中汞离子有优异的去除效果,其吸附容量可达212.13 mg/g;吸附等温线符合Langmu ir单层吸附模型,动力学过程符合准二级动力学模型;溶液pH值对吸附影响不是很大,pH 5-10范围都有较好的吸附效果;氯离子易与汞离子形成水溶性更强的络合物,对共聚物的吸附有很大的抑制作用。 The adsorption properties of mercury ion onto a novel copolymer poly（aniline-co-o-aminophenol）,which was synthesized by chemically oxidative polymerization,were studied by a batch system.The results showed that poly（aniline-co-o-aminophenol） had excellent adsorption ability for mercury ion and Qmaxincreased to 212.13 mg/g.Mercury adsorption isotherm onto poly（aniline-co-o-aminophenol） was well described by Langmuir model and the adsorption could be approximated more favorably by the pseudo-second-order model.The pH of solution had a little impact on adsorption.The copolymer had good adsorption ability when the pH of solution was 5-10.The existence of chloride ion decreased adsorption significantly because of its complexation with mercury ion.
