The acceleration effects of surfactants on the reduction of dichlorophenol indophenol (DPIP) with diphenylcarbazide as a reductant were investigated. The surfactants used were acidic, cationic, zwitterionic and nonionic species. Each surfactant showed its maximum acceleration effect at the concentration approximate to its CMC. Zwitterionic sulfobetaine-14 apparently accelerated the reaction by 32 times at pH 5.5, which was the largest value among those given by the surfactants tested. Soybean asolectin also showed the acceleration activity irrespectively whether it was sonicated or not. From absorption change of DPIP in the presence of surfactants and partition efficiencies of the reactants in n-dodecane, the mechanism of the acceleration was discussed relating to the location and microenvironmental pH of the reactants.
