Abstract

Various electrochemical tests were carried out to elucidate the electrolytic oxidation mechanism of oxalic acid on a boron-doped diamond electrode in a nitric acid environment. These included cyclic voltammetry, AC impedance, constant current electrolysis, and electron paramagnetic resonance spectroscopy. The impact of electrode potential, current density, nitric acid concentration, and electrode plate spacing on the oxidation of oxalic acid was investigated. In the electrolysis mechanism, indirect oxidation ofOH plays a major role and direct oxidation at the electrode plays a minor role. Excessive nitric acid concentration will reduce the electrooxidation rate of oxalic acid. The optimal process conditions for electrolyzing oxalic acid are obtained as follows: the plate spacing is 2 cm, and the current density is 60 mA cm. Finally, the BDD electrode can electrolyze the oxalic acid concentration to below 0.001 mol/L, which can meet the process requirements.

摘要

进行了各种电化学测试，以阐明在硝酸环境中草酸在硼掺杂金刚石电极上的电解氧化机理。这些测试包括循环伏安法、交流阻抗、恒电流电解和电子顺磁共振光谱。研究了电极电位、电流密度、硝酸浓度和电极板间距对草酸氧化的影响。在电解机理中，OH的间接氧化起主要作用，电极上的直接氧化起次要作用。过高的硝酸浓度会降低草酸的电氧化速率。得到了电解草酸的最佳工艺条件如下：板间距为2 cm，电流密度为60 mA/cm²。最后，BDD电极可将草酸浓度电解至0.001 mol/L以下，满足工艺要求。
