摘　　要：以环氧氯丙烷为交联剂合成的β-环糊精聚合物树脂与1-(2-吡啶偶氮-2-萘酚形成的包结络合物能与多种金属离子形成稳定的吸附络合物.本文报道了以这种包结络合物吸附富集铜、镉、镍与锰的实验条件以及用原子吸收分光光度法测定痕量铜、镉、镍与锰的研究.实验中详细地研究了有关的吸附条件及富集倍数,提出了一种富集与测定痕量金属的新方法.An inclusion adsorbing resin was prepared by inclusion of α-pyridylazo-β-naphthol using β-CD cross-linked polymer. The resin could adsorb many metal ions to form stable adsorbing complexes. The experimental conditions and related physical and chemical properties of enrichment of copper, cadmium, nickel and manganese ions by above-mentioned inclusion resin were investigated. It was found that the enrichment multiples for studied metals were 50. A method for the enrichment and determination of trace copper, cadmium, nickel and manganese by AAS has been developed.
