Abstract :
The kinetics of the photo-oxidation of dicarboxylic acids by chloramine-T (CAT) in an aqueous medium has been studied. The acids selected for the study are glutaric acid and adipic acid. It is found that reaction obeys first order kinetics with respect to the oxidant (CAT). The reaction shows zero order dependence with respect to substrates. The reaction is found to be catalysed by H+ ions. Different parameters like the effect of the variation of concentration of the reactants, product and intensity of light on the reaction rate have been studied. A suitable mechanism has been proposed depending on the experimental findings.

Key-Words / Index Term :
