| 摘 要： | 本文研究了溴酚蓝和醌亚胺类染料离子的缔合性质，取代基对缔合物的稳定性、可萃性的影响。二者随取代基的碱性和亲水性的增大而降低，取代基还影响染料缔合物的光学性质，其中溴酚蓝－亚甲蓝体系的灵敏度最高（ε＝１．３×１０ ５Ｌ／ｍｏｌ／ｃｍ），稳定性最大（Ｋｓｐ＝８．３×１０－１５），可用于双显色剂协同增敏萃取分析。

| Abstract: | The properties of bromophenol blue and quinone-imine dye ion-pair complex were studied.The influence on the stabitity and extractability of the complex of substituents in the dyes was discussed.It was found that such influence decreases with the increase in basicity and hydrophilicity of the substituents,the substituents also influence the optical properties of the dye complex.Bromophenol blue and methylene blue ion-pair complex system exhibited sensitivity(ε=1.3×10￣5 L·mol￣-1.·cm-1)and strong stability.It can be used in the spectrophotometric analysis of simultaneous effect of bino-developers. |
