摘要：
The Ru(III) catalyzed oxidation of ethylenediaminetetraacetic acid by N-bromosuccinimide in aqueous alkaline medium was found to occur via substrate-catalyst complex formation in equilibrium step followed by the interaction of oxidant species and complex in a slow step to yield the products with regeneration of catalyst. A mechanism involving hypobromate ion as the reactive species of the oxidant has been proposed. The rate constants of individual steps of the reaction mechanism have been evaluated, and used to regenerate rate constants.
