Studies on Catalytic Oxidation of Glycollic Acid by PMS

Abstract

The kinetics of the reaction between peroxomonosulphate with glycolic acid was studied in the presence of Mn (II) in the pH range 4.05 to 4.75 at 304K. The reaction followed first order with respect to peroxomonosulphate.  The rate of the reaction increases with the [Mn (II)] and independent with respect glycolic acid.  A plot of k_obs vs 1/ [H⁺] is a straight line passing through origin. Based on the results a rate equation, kinetic scheme and a most probable mechanism has been predicted.
