摘要 应用循环伏安法研究了Fe(III)-草酸-葡萄糖酸钙媒质体系的电化学行为及其可能的反应机理.实验表明,Fe(II)-葡萄糖酸盐起着最终的还原作用.电解还原时间、工作电压和阴极面积这3个因素影响着电流效率,在Fe(III)-草酸-葡萄糖酸钙媒质体系中,还原大红R的电流效率最高可达89%,其电解还原时间10 min,工作电压4 V,阴极面积40 cm2. The electrochemical behavior and possible reaction mechanism in Fe（III）-oxalate-calcium gluconate system were studied by cyclic voltammetry.The results showed that Fe（II）-gluconate was the final reductant.The reduction time,the working voltage and the cathode area influenced the current efficiency.The high current efficiency of 89% for the indirect electrochemical reduction of Vat Scarlet R could be achieved with reduction time of 10 min,working voltage of 4 V and cathode area of 40 cm2 in Fe（III）-oxalate-calcium gluconate system.
