氢化物发生—分光光度法测定染发剂中的微量铅

Determination of Trace Lead in Hair Dyes with Hydride Generation-Spectrc-photometry

本文提出了用铁氰化钾将铅氧化至高价,再用氢化物发生-分光光度法测定铅的一种新方法。该法灵敏度高,简便快速,用于分析染发剂中的铅,取得了较好的效果。

A new method is presented to determine trace of Pb. The lead is oxidized to high valendwith potassium ferricyanide and deiermined by hydride generation-spectro-photometry. Themethod is sensitive, simple and rapid. The result of determination of lead in hair dyes showsbetter effect.
