水溶性卟啉的合成及与铜（Ⅱ）显色反应的研究

SYNTHESIS OF MESO-TETRAKIS[P-(α-ACE-TANILIDEYL)DIMETHYLAMMONIUMPHENYL] PORPHINE CHLORIDE[T(4-AMAP)P]AND SPECTROPHOTOMETRIC STUDY OF ITS COLOUR REACTION WITH COPPER(Ⅱ)

合成了水溶性ｍｅｓｏ－四［４－二甲基－（α－乙酸苯胺基）铵苯基］卟啉［简称Ｔ（４－ＡＭＡＰ）Ｐ］．并用分光光度法研究了它与Ｃｕ（Ⅱ）的显色反应，确立了最佳配位条件，测定了配合物的摩尔吸光系数以及配合物的组成．该方法可用于水中痕量铜的测定．

A new water soluble porphine,meso-tetrakis[P-(a-ace-tanilideyl) dimethylammoniumphenyl]porphine chloride [T(4-AMAP)P] was synthesized、Its colour reaction with copper(Ⅱ)was studied by spectrophotometry.Suitable reac tion condition were established.The molar absorptivities (ε=5. 29×105L· mol-1·cm-1)and connposition of the complex(1:1) Were also determined. Beer's law is obeyed in the range of 0～100ppb for copper(Ⅱ).The method can be applied to the determinationof microamounts of on(Ⅱ)in water.
