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三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10min,工作电压4V,阴极面积40cm2。

Abstract: 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.

Key words: cyclic voltammetry (CV), current efficiency;working voltage, cathode area, Fe(Ⅲ)-oxalate-calcium gluconate system;cotton dyeing
