Abstract

Kinetics of Mn(VII) oxidation of L-histidine in aqueous sulfuric acid medium has been studied spectrophotometrically. The reaction shows a first order dependence both on [Mn(VII)] and [histidine] in moderately sulfuric acid medium. The reduced product of the oxidant, Mn(II), catalyzed the reaction. Both catalytic and non-catalytic processes were determined to be first order with respect to permanganate ion and to the histidine. Dependence of reaction rate on temperature is examined and activation parameters have been evaluated using Arrhenius and Eyring plots. Finally, a mechanism consistent with the observed kinetic data has been proposed and discussed.
