| 摘 要： | 合成了新显色剂1-偶氮苯-3-噻唑-三氮烯（ABTT）．并研究了它与锌的显色反应。在pH11．0的Na284O7-NaOH缓冲溶液中，Triton X-100表面活性剂存在下，试剂与锌生成4：1的红色配合物。配合物的最大吸收峰位于525nm，表观摩尔吸光系数为2．7×10^4L·mol^-1cm^-1。Zn^2＋浓度在0-460μg／L范围内符合比尔定律。用拟定方法测定工业废水中微量锌，结果满意。

| Abstract: | The 1-azobenzene-3-thiazoly-triazene （ABTT） as a ehromogenie reagent was synthesized and its color reaction with zinc has been investigated. In the presence of the surface active agent Triton X-100 and in the Na2B4O7-NaOH medium of pH 11.0,ABTT forms a red complex with Zn（ II ）. The apparent molar absorbtivity of the complex is 2.7×10^4L·mol^-1cm^-1 at 525nm（λmax）.The molar ratio of Zn（ Ⅱ ） to ABTT is 1：4. Beer,s law is well obeyed in the range of 0-460μg/L for zinc. The method has been applied to the direct determination of cadmium in waste water with satisfactory results. |
