【摘要】 介绍了氨替比林基重氮氨基偶氮苯的合成方法。用光度法测定的它在 Triton X-100存在下的二级离解常数分别为（6.0±0.3）×10^-2,（5.9±0.4）×10^-12。在 pH11.5时,与镉和汞的配合物的表观摩尔吸光系数分别是2.11×10⁵L·mol^-5·cm^-1和1.61×10⁵L·mol^-1·cm^-1。更多还原

【Abstract】 This paper described the method of synthesisof antipyrinyldiazoaminoazobenzene（Cadion AP）.Its dissociation constants were determined byspectrophotometry in the presence of Triton X-100.They are K-（a1）=（6.0±0.3）x10^-2and K_a2=（5.9±0.4）×10^-12respectively.The colour reac-tion of Cadion AP with metal ions was studiedat pH 11.5 and in the presence of Triton X-100,the apparent molar absorptivities of complexesfor Cd（Ⅱ）,Hg（Ⅱ）are 2.11×10⁵ and 1.61×10⁵L.mol^-1·cm^-1respectively.更多还原
