摘要/Abstract

摘要： 从电催化氧化降解有机污染物的机理出发，研究了草酸在Ti/IrO2-Ta2O5阳极圆柱形电解槽中的电催化氧化过程，建立了描述整个降解过程的瞬时电流效率与溶液本体有机物浓度的关系式. 通过实验对模型进行了验证，实验结果与模型计算结果基本一致，并讨论了误差产生的原因.

Abstract: The electrocatalytic oxidation degradation kinetics of oxalic acid in a cylindrical electrochemical reactor with Ti/IrO₂-Ta₂O₅ 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 resultswere reasonably consistent with the established kinetic model. Furthermore, the competition between the two paths was explored with the modelparameter analysis.

Key words: electrochemical oxidation, Ti/IrO₂-Ta₂O₅ , anode, oxalic acid, theoretical model
