Abstract

The series of catalysts like acetate, oxalate, EDTA, the varies micelles viz, CTAB, SDS, TRITON X-100 was carried out in the kinetic study of oxidation of Thiourea by Cr(VI) as an oxidant in water medium. The effect of catalytic efficiency has been study for varies catalyst and micelles by volumetric method and UV spectroscopic methods. The product was confirmed by IR studies. UV study reveals shows that higher catalytic efficiency has been studied in the presence of oxalate, SDS medium. The effect of catalytic efficiency also has been study for ionic strength, solvent variation, polymer, different temperatures, and Thermodynamic parameters and varied the [Thiourea] in the presence of different micelles at constant concentration. The UV–Visible spectroscopic results revealed that the oxidation reaction exhibited significantly enhanced catalytic efficiency in the presence of oxalate as a catalyst and SDS as the micellar medium, indicating their superior ability to accelerate the oxidation process compared with other tested systems. In addition to catalyst and micelle variation, the influence of several physicochemical parameters on the reaction kinetics was also examined in detail. These included ionic strength, solvent composition, polymer additives, temperature variation, and thermodynamic parameters to understand their role in modulating the oxidation mechanism. Furthermore, the concentration of thiourea was systematically varied under constant catalyst and micelle concentrations to investigate substrate dependency and reaction order in different micellar environments.

Keywords: Chromium, thiourea, micelles, ligands, spectral studies
