Abstract EN
The kinetics and mechanism of the reduction of chromium(VI) by lactic acid (Lac) in aqueous acidic medium was studied with spectrophotometry in a temperature range of 298.15 K~313.15 K.
Under the conditions of the pseudo-first order ([Lac]0≫[Cr(VI)]0), the observed rate constant (kobs) increased with the increase in [Lac] and [H+].
There is no salt effect.
Based on the experimental results, a probable reaction mechanism of oxidation was proposed.
The rate equation derived from the mechanism could explain all the experimental phenomena.
Activation parameters along with rate constant of the rate-determining step have been evaluated.
