Abstract
Oxidation of glycolate ions with Na2S2O8 + RuCl3 mixture in 0.2 M NaOH was studied by spectrophotometry. Glycolate is oxidizd to oxalate at 20–70°C. The reaction of glycolate with persulfate follows the first-order rate law with respect to [S2O 2−8 ], weakly depends on the glycolate concentration, and accelerates with increasing the Ru(III) content from 2 × 10−5 to 1 × 10−4 M. Further increase in the Ru(III) concentration does not affect the reaction rate. Probable reaction mechanism was considered.
