摘要: 用卟啉衍生物光度法测铜的研究已有报导[1—8]。我们对具有新型结构的α、β、γ、δ-四-(4-二甲氨基苯基)卟啉[简称T(4-DMAP)P)与铜反应的分光光度法进行了研究。结果表明:用T(4-DMAP)P测定痕量铜具有灵敏度高(ε412=3.9×105)、选择性好及操作简便等特点。应用于水样和铝合金中铜的直接测定,结果令人满意。

Abstract: In this paper, the complex reaction of α,β,γ,δ-letra-(4-dimethylaminophenyl) porphine[T(4-DMAP)P]with copper (Ⅱ) in the presence of anionic surfactant, sodium dodccyisulfat and small amounts 01 hydroxylamine has been studied. The water insoluble porphine was found to be a new highly sensitive and highly selective reagent for the direct spectropholometric determination of the ultramicro amount of copper.
