摘　　要：本文合成了新显色剂对乙酰基苯重氮氨基偶氮苯。研究了各种表面活性剂对镉（Ⅱ）一试剂体系的增敏作用。并以铜（Ⅱ）一试剂－表面活性剂建立了三种光度法测镉的新显色体系。通过比较，讨论了显色体系的分析性能与试剂结构及显色条件的关系。A new color reagent P- Acetylbenzenediazoaminoazobenzene(p-AcDAA) has been synthesized. We found thatCd（Ⅱ）-p-AcDAA complex could be sensitited by no nionic surfactants， anionic surfctants and nonionic-anionic mixedsurfactant．Three new methods for spectrophotometric determination of trace cadmium have developed on the system of Cd（Ⅱ）-p-AcDAA-SF.The relationship between the analytical properties of color reaction, structure of the reagents and the color condition have been also described by comparison of proposed method.
