摘　　要：以交联聚苯乙烯树脂为原料,经硝化、还原、重氮化和偶联反应,合成了含8-羟基喹哪啶功能基的新型螯合树脂(PS-HQD)。研究了新螯合树脂对铜离子的吸附性能。实验结果表明,在pH 6.0时,静态饱和吸附容量为25.72 mg/g树脂。一次洗脱回收率达95.42%。吸附过程符合Langmu ir和Freund lich模型。A crosslinked polystyrene supported 8-hydroxyquinaldine was synthesized by the process of nitrification, reduction, diazotization and coupling reaction, and its adsorption for Cu^2＋was studied. Result showed that the new resin had good adsorption for Cu^2＋ , with the statically saturated adsorption capacity of 25.72mg/g and the first desorption rate of 95.42% when pH was 6.0. The adsorption process was accord with Langmuir and Freundlich models.
