摘要
本文以环氧氯丙烷为交联剂，与β-环糊精发生反应，合成一种具有三维网状结构并不溶于水的大分子物质。将该物质与显色剂PAR作用，生成一种包结化合物树脂。用该树脂富集痕量汞离子，结果令人满意。
In this paper. β-cyclodextrin polymer has been synthesized using epichlorohydrin as crosslinking agents. The polymer can form stable inclusion complexes with 4- (2pyridylazo) resorcinol. In an appropriate condition, inclusion complexes can selectly enrichmercury. The results were satisfactory.
