摘　　要：目前,已见报导用非水溶性卟啉化合物测定铜的有:TPP、TF(cooEt)P。本文研究了在表面活性剂存在下,非水溶性卟啉TTP与铜络合反应的条件,试验了多种离子和盐的干扰情况。结果表明,此方法灵敏度较高(ε414=4.5×105),准确性较好,操作简便,可用于水样、铝合金和矿石中微量铜的直接测定。In this paper,α,β,γ,δ-tclra-(4-methylphenyl) porphinc(TTP) has been prepared by the reaction of 4-tolualdehyde with pyrrole.The complex formation reaction of TTP with coppcr(Ⅱ) in the presence of anionic surfactant,sodium dodecyl benzene sulf’onate has been studied.The water-insoluble TTP was found to be a highly sensitive and highly selective reagent for direct spcctropliolomclric determination of ultramicro amount of copper.The Soret band of coppcr(Ⅱ)-TTP complex lies at 414nm,which was well separated from that of diacid form of TTP (444).The composition of the complex is coppcr(Ⅱ) TTP=1:1.Apparent molar absorption coefficient is 4.5×105.The interference of 23 ions and 6 salts was examined and found to be mininal.This simple and rapid method has been used for the analysis of copper in water sample,ores and Al alloy with satisfactory results.
