摘要

The kinetics of fading of rosaniline hydrochloride (RA(+)) by periodate (IO4-) was studied in two different reverse micellar systems' AOT/heptane and CTAB/CHCl3/hexane. The reaction between RA(+) and IO4- obeys first order kinetics with respect to RA(+) and IO4- in both the reverse micellar media. In the AOT system, the pseudo-first order rate constant was found to be fifteen times greater than in aqueous medium, while in the CTAB reverse micellar system the rate increases by three hundred times. The significant increase in reverse micelles is attributed to the unique properties of the water pools. The study was carried at different surfactant concentrations and different W (= [H2O]/[Surfactant]) values. The Berezin pseudo phase model was used to explain the effect of surfactant. The activation parameters determined in the presence of reverse micelles and aqueous medium also account for the large acceleration in the presence of reverse micelles.
