2,4-二氟苯重氮氨基偶氮苯的合成及其与镉(Ⅱ)配合物的性质

Synthesis of 2,4-Difluorobenzenediazoaminoazobenzene and Study on the Properties of Its Complex of Cadmium

合成了新三氮烯试剂 2 ,4 -二氟苯重氮氨基偶氮苯 ,研究了该试剂与镉形成配合物的最佳条件及配合物的性质 ,并利用该试剂与镉形成配合物的性质建立了分光光度法测定镉的新方法 ,成功地应用于水样中的镉的分析。

A new triazene reagent-2,4-difluorobenzenediazoaminoazobenzene has been synthesized.The reaction condition of the complex of the reagent with cadmium was optimized and the properties of the complexes were studied.A new method for spectrophotometric determination of trace cadmium was developed based on the properties of the complex.The proposed method was applied to the determination of trace cadmium in water samples with satisfactory results.
