✦ Synopsis

The redox reaction Br -ϩ BrO 3 -has been studied in aqueous zwitterionic micellar solutions of N-tetradecyl-N, N-dimethyl-3-ammonio-1-propanesulfonate, SB3-14, and N-hexadecyl-N,N-dimethyl-3-ammonio-1-propanesulfonate, SB3-16. A simple expression for the observed rate constant, k obs , based on the pseudophase model, could explain the influences of changes in the surfactant concentration on k obs . The kinetic effect of added NaClO 4 on the reaction rate in SB3-14 micellar solutions has also been studied. They were rationalized by considering the binding of the perchlorate anions to the sulfobetaine micelles and their competition with the reactive bromide ions for the micellar surface.
