The decomposition rate of oxalate by hydrogen peroxide has been investigated by a KMnO4 titration method. The rate equation for decomposition of hydrogen peroxide in the aqueous phase was obtained. The acid-catalytic effect was shown up at over nitric acid concentration 2M. The rate equation for the decomposition of oxalate by hydrogen peroxide was newly proposed. The rate constant for decomposition of oxalate increased with nitric acid concentration and the effect of hydrogen ion concentration was expressed. The neodymium oxalate was dissolved by nitric acid and the resulting solution was decomposed by hydrogen peroxide.
