Abstract :The kinetics of redox reaction between N-benzoylleucomethylene blue (BLMB) and iron (3) ions were investigated by using stopped flow spectrophotometric techniques in water, water-ethanol, SDS, DTAB and Brij 35 micellar solutions each containing sulfuric acid. In SDS solutions, the rate constant abruptly increases with increasing concentration of SDS around cmc, and reaches almost 150 times as large as that in water at the maximum point, then decreases gradually with further increase in SDS concentrations. The values of the rate constant both in DTAB and Brij 35 solutions are, on the other hand, about same as that in water. In water-ethanol mixed solvent, the slightly smaller value was obtained. These results could be explained by considering the protonation of BLMB and its location in aqueous micellar solutions.
