摘要：

The kinetics of oxidation of ethylenediaminetetraacetic acid (Red) and nitrilotriacetic acid (Red) by trisacetatomanganese(III) dihydrate in dilute sulfuric acid and dilute perchloric acid media in nitrogen atmosphere were studied, where Red denotes the reductant in these reactions. At constant [Red], [H+], ionic strength and temperature, a first order dependence with respect to [Mn(III)] was observed. The rate increased with [Red] but was independent at higher [Red]. The rate was unaltered by the changes in [H+], ionic strength and added Mn(II). A suitable mechanism has been proposed to explain the observed kinetic data.
