本文研究了80°C水溶液中草酸在Au上的阳极氧化。在单位离子强度的H2SO4+ K2SO4+ KOH溶液中，测定了反应速率随电位、草酸浓度、pH和温度的变化。草酸在酸性介质中被氧化成CO2。反应速率与pH和未解离草酸均呈一级关系，第一步脱羧反应为速率决定步骤。
The anodic oxidation of oxalic acid on Au has been studied at 80°C in aqueous media. The reaction rate was measured as a function of potential, oxalic acid concentration, pH, and temperature in H2SO4+ K2SO4+ KOH solutions of unit ionic strength. The oxalic acid was oxidized in acidic media to CO2. A first-order dependence of the rate on both pH and undissociated oxalic acid was found. The first decarboxylation step appears to be rate determining.
