摘　　要：Abstract: A new triazene reagent 1-(2-benzothiazolyl)-3-(4-phenylazoghecyl )-triazece (BTPAPT) has been synthesized.The clour reaction of STPAPT with Cd (Ⅱ) has been studied. At pH=9～11,in the presence of Triton X-100,the reagent with Cd (Ⅱ) forms a complex with high sensitivity, the molar ratio of Cd (Ⅱ) to BTPAPT is 1: 2. The molar absarptlvity is 1. 4 × 10-5 L. mol-1. cm-1. Beer's law is obeyed for Cd (Ⅱ) in the range of 0-14 μg/25ml.Abstract: A new triazene reagent 1-(2-benzothiazolyl)-3-(4-phenylazoghecyl )-triazece (BTPAPT) has been synthesized.The clour reaction of STPAPT with Cd (Ⅱ) has been studied.
