The influence of sodium lauryl sulfate (SLS) micelles on the kinetics of Ag(I)-assisted oxidation of  l -Leucine (L-Leu) by acidic Mn(VII) has been explored within aqueous environments. The advancement of the reaction is evaluated through the quantification of reduction in absorption value, utilizing the pseudo-first-order situation as a metric for [SLS], [Ag(I)], [L-Leu], ionic strength, [Mn(VII)], and [H + ]. Throughout the investigated concentration spectrum, the reaction exhibits fractional-second-order reliance on [H + ], first-order dependence on [Mn(VII)], and fractional-first-order dependency on [L-Leu] and Ag(I). Ag(I) markedly enhances the oxidation rate by a factor of 3.4. The kinetic profile revealed a 2.8-fold improvement in the rate constant associated with a rise in surfactant content. The combined action of Ag(I) and SLS micelles results in a 9.6-fold augmentation in the oxidation rate of L-Leu. The oxidation process is accelerated by the electrostatic interaction that occurs among the Mn(VII) and negatively charged micelle, which brings the oxidant closer to the substrate (L-Leu), which is normally soluble in a micellar milieu. A plausible mechanistic scheme that aligns with the kinetic observations has been highlighted, along with an examination of the Piszkiewicz model, to further explain the evident catalytic effect of SLS micellar surroundings.
