Abstract

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. e =1.3×10 5L·mol -1 ·cm -1 .
