水样中痕量Ca(Ⅱ)富集方法的研究

Study of enrichment method for trace calcium (Ⅱ) in water sample

本文以环氧氯丙烷为交联剂，与β－环糊精反应，生成一种具有三维网状结构且不溶于水的稳定大分子物 质。该物质与络合剂酸性铬蓝Ｋ作用，形成包结树脂。用该树脂富集水中痕量Ｃａ（Ⅱ），取得了较满意的结果。

Synthesized with β-cyclodextrin using epichlorohydrin as crosslinking agents in the paper. the macromolecules are insoluble, three-dimensional and netted. The substance can form stable inclusion resin with organic ligands. such as acid chrome blue K. The application of the resin to enrich trace calcium (Ⅱ) in water sample reached satisfactory results.
