【摘要】 <正> 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。更多还原

【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.更多还原
