泡沫塑料柱色谱法纯化可溶性锌（镉）盐

Purifying the Soluble Zinc(Cadmium)salts with Foam Plastics Chromatographic Column

研制出复合泡沫塑料色诸柱，并且将其用于可溶性锌（镉）盐的深度纯化，除去重金属杂质离子Ｆｅ￣（２＋）、Ｃｒ￣（３＋）、Ｍｎ￣（２＋）、Ｐｂ￣（２＋）、Ｃｕ￣（２＋）、Ｃｏ￣（２＋）和Ｎｉ￣（２＋），快速而效果显著。

The deep purifing system is made up from 4 kinds of foam plastics column con-taining respectively active MnO2, NaBiO3, cadmium(zinc) diethylaminothiocarbamate anddimethylglyoxime in series. When a solution of zinc or cadmium sulfate flows through thesvstem the content of Fe2+, Cr3+, Mn2+, Cu2+, Pb2+, Co2+ and Ni2+ in it can be decreasedrapidly and simply from 1～10μg/g to less than 0.1～0. 5μg/g.
