摘    要:研究了1-(偶氮苯基)-3-(4,5-二甲氧基-2-苯甲酸)-三氮烯(ABDMBAT)试剂与Cu(Ⅱ)的显色反应。在TritonX-100的存在下,pH 11.0的Na2B4O7-NaOH缓冲溶液中,该试剂与铜形成红色络合物,ABDMBAT与Cu(Ⅱ)形成的络合物的最大吸收峰位于540nm处,表观摩尔吸光系数ε=8.26×104L.mol-1.cm-1,Cu(Ⅱ)在0—14μg/25mL范围内服从比耳定律。

关 键 词:1-(偶氮苯基)-3-(4  5-二甲氧基-2-苯甲酸)-三氮烯  铜(Ⅱ)  显色反应

Abstract:A new chromogenic reaction of 1-(azobenzene)-3-(4,5-dimethoxy-2-benzoic acid)-triazene(ABDMBAT)with Cu(Ⅱ) was investigated.In the presence of the surface active agent TritonX-100,the reagent formed a red complex with copper in the Na2B4O7-NaOH medium of pH 11.0.The maximum absorption wavelength of the complex that was formed by ABDMBAT with Cu(Ⅱ) was at 540nm with the apparent molar absorptivity coefficient of 8.26×104L·mol-1·cm-1.Copper(Ⅱ) obeyed Beer's law in the range of 0—14μg/25mL.
Keywords:1-(Azobenzene)-3-(4  5-Dimethoxy-2-Benzoic Acid)-Triazene  Copper(Ⅱ)  Color Reaction
