英文摘要：

The electrocatalytic oxidation degradation kinetics of oxalic acid in a cylindrical electrochemical reactor with Ti/IrO2-Ta205 as an anode was studied. The relation between instantaneous current efficiency and organic concentration in bulk was established based on the two paths for direct electrochemical oxidations, and the theoretical model was verified by experiments. The experimental results were reasonably consistent with the established kinetic model. Furthermore, the competition between the two paths was explored with the model parameter analysis.
