摘要

本文对高灵敏度显色剂α.β.γ.δ—四苯基卟啉（TPP）与锰（Ⅱ）的配合反应作了较系统的研究

找到了显色反应的最佳条件

在此基础上建立了用TPP测定微量猛（Ⅱ）的光度分析法

并测定了常见的8种共存离子的最大允许量。本方法操作简便、灵敏度高

TPP锰（Ⅱ）配合物在466nm的表观摩尔吸光系数为1.14×10

用于人发中微量锰的测定

结果令人满意

Abstract

The a

tetraphenyl porphyrin (TPP)

a highly sensitive reagent for direct spectrophotometric dertermination of ultramicro quantities of metals

has been syhthesized. The complex reaction of TPP with Mn(II) has been studied. A sensitive method for the determination of trace Mn(II) with TPP has bocn established. The apparent molar absorptivity of the Mn(II) complex is 1.14x105L. mol.-1cm-1at 466nm. The method has been applied to the determination of trace Mn in human hair with satisfactory results
