KINETICS AND MECHANISM OF OXIDATION OF AZO DYE ACID YELLOW 36 BY CHLORAMINE-T IN HYDROCHLORIC ACID MEDIUM
Journal Title: Indo American Journal of Pharmaceutical Research - Year 2017, Vol 7, Issue
Abstract
Abstract Kinetics of oxidative decolorization of Acid yellow36 (AY36) by chloromine-T,(CAT) in hydrochloric acid (HCl) medium at 301 K has been investigated spectrophotometrically at λmax439nm. The reaction showed first order dependence on [CAT] and[AY36]o and inverse fractional order dependence on [HCl]. Stoichiometry of the reaction was found to be 1:3 with respect to the substrate and oxidant respectively. The oxidation products were identified by spectral analysis. Variation of ionic strength had no effect on the rate. Addition of p-toluene solfanamide (PTS)retarded the rate of reaction. Activation parameters have been computed. Probable mechanism and the relevant rate law have been deliberated for the observed kinetic results.
