| 摘 要： | 介绍了邻羧基苯基重氮氨基－４－苯基－２－噻唑（ＣＰＤＡＰＴ）的合成方法，并研究了在混合表面活性剂ＯＰ－ＳＤＳ存在下，它与钯（Ⅱ）的显色反应。结果表明，在ｐＨ６．４～７．０范围内，钯（Ⅱ）与该试剂形成１∶２红色配合物，其最大吸收峰位于４９０ｎｍ，摩尔吸光系数为２．４７×１０５Ｌ·ｍｏｌ－１·ｃｍ－１。Ｐｄ（Ⅱ）在０～５μｇ／２５ｍＬ范围内符合比尔定律。方法用于催化剂中微量钯的测定，结果满意。

| Abstract: | his paper described the method of synthesis of ocarboxylphenyldiazoamino4phenyl2thiazole(CPDAPT) and its colour reaction with palladium.The results show that in the medium of pH6.47.0 and in the presence of OPSDS,palladium() reacts with CPDAPT to form a red complex with the molar ratio of 12.The complex exhibits maximum absorption at 490nm with a molar absorptivity of 2.47105 Lmol-1cm-1.Beers law is obeyed in the range of 05 g/25mL Pd().The method has been applied to the determination of microamounts of palladium() in PdC catalyst with satisfactory results. |
