本文研究了用ｍｅｓｏ-四（对磺基苯）-卟啉为试剂二阶导数分光光度法测铜的分析方法及最佳条件。结果表明，在ＰＨ＝３．２～５．８溶液中。Ｃｕ与ＴＰＰＳ４生成黄绿色的配合物，最大吸收波长为４３２ｎｍ，Ｃｕ含量在５～３０μｇ／１范围内有很好的线性关系。用该法测定了人发中铜的含量，结果令人满意。
In this paper, the analytical method and the optimum conditions of copper determination by meso-tetrakis (p-sulfophenyl) -porphyrin reagent as second-order derivative spectrophotometry were studied. The results show that in PH = 3.2 ~ 5.8 solution. Cu and TPPS4 generated yellow-green complexes, the maximum absorption wavelength of 432nm, Cu content in the range of 5 ~ 30μg / 1 has a good linear relationship. The method was used to determine the content of copper in human hair with satisfactory results.
