摘　　要：β 环糊精交联聚合物包结有机显色剂8 羟基喹啉所形成的配合物树脂可与多种金属离子反应生成包结配合物。报道了β 环糊精交联聚合物包结8 羟基喹啉以及形成的配合物树脂吸附铜的实验条件的研究。结果表明:在pH7、200mL L乙醇的溶液条件下,可制备β 环糊精交联聚合物包结8 羟基喹啉的包结吸附树脂;该包结树脂可从稀溶液中吸附铜,富集倍数达到100。The inclusion absorbing resin of 8-hydroxyquinoline with β-cyclodextrin cross-linking polymer could react with many kinds of metal ions to form absorbing complexes. The experimental condition of the inclusion and enrichment of copper were investigated. The results showed that in the solution of ethanol at pH 7, the inclusion absorbing resin could be preparaed by inclusion of 8-hydroxyquinoline with β-cyclodextrin cross-linking polymer. The resin could enrich copper from dilute solution with enrichment coefficient of 100.
