摘要
本文研究了酸性染料溴酚蓝和碱性染料亚甲蓝以及二者所形成离子对缔合物的吸光性质，测定了它们的缔合能力，Ｋｓｐ＝８．３×１０－１５，离子对在二氯乙烷中的萃取率为９１％，离子对形成后溴酚蓝的最大吸收波长红移同亚甲蓝等色化，缔合物在二氯乙烷中的ε＝１．３×１０５Ｌ·ｍｏｌ－１·ｃｍ－１。为高灵敏度双显色剂的应用找到了新途径。
The spectrophotometric characters of acid bromophenol blue dye and basic methylene blue dye and their ion pair complexes was studied.The K sp =8.3×10 -15 and the extractibility of the bromophenol blue dye ion pair system is 91%.The iso chromatic dye ion pair are simulitaneously extracted by 1,2 dichloroethane. ε =1.3×10 5L·mol -1 ·cm -1 .
