水样中痕量Cr(VI)的富集及测定

Enrichment and Determination of Trace Cr (VI) in Water Sample

本文以环氧氯丙烷做交联剂，与β-环糊精反应，合成一种具有三维网状结构并不溶于水的大分子物质。该物质与显色剂朱基萤光酮发生包结作用，形成包结树脂。用此树脂富集痕量Cr（VI），结果令人满意。

Insoluble macromolecule polymer has been synthe sized with three -dimensioned and netted structure using epichlorohydrin as crosslinking agents in the paper. Thepolymer formed inclusion resin with PF. The resin was used to enrich trace Cr (VI) in thewater sample, the results were satisfactory.
