Abstract

Abstract—Spectrophotometric investigation of oxidative degradation of an azo-dye Acid Red 18 (AR18) by Chloramine-T (CAT) and Chloramine-B (CAB) as oxidizing agents in HCl medium has been reported. Effect of dye, oxidant and HCl concentration on rate was investigated under pseudo first order conditions. The addition of NaClO4, chloride ions showed no effect on the rate of oxidation.Addition of the reduction product p-toluenesulphonamide retarded the rate of reaction. The dielectric effect studied by adding different volume of methanol indicated decreased rate with increase in dielectric constant. Kinetic studies revealed first-order dependence of rate on each oxidant, dye and a fractional order dependence on HCl with both the oxidants. However, rate of oxidation of dye by CAB was found to be faster compared to CAT. The stoichiometry of the reaction and the oxidation products were found to be same with both the oxidants. The reaction was studied at different temperatures and the activation parameters were estimated. Based on experimental results, the rate law was deduced and a plausible mechanism is put forward.
