Kinetic and Mechanistic Study of the Reduction of Chromium(VI) by Lactic Acid

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
