The pseudo ﬁrst-order rate constant (k ) of the oxidation reaction is directly proportional to obs ? ? [H ] and [promoters], which indicates that the reaction is ﬁrst order with respect to H and promoters. The reaction was conducted at four different temperatures from which the activation parameters were calculated. Proton nuclear magnetic resonance ( H- NMR) studies were performed to detect the location of reactant molecules in nanometer- sized micelles. From the observed kinetic results, a suitable mechanism consistent with the rate law has been proposed. The micelles produced a catalytic effect in the entire range of sodium dodecylsulphate (SDS) concentrations used, and the effect is explained by pseudo-phase ion exchange.
