摘　　要：以黄金电极作为工作电极,研究Fe(Ⅲ)-草酸-葡萄糖酸钙媒介体系的电化学性质,循环伏安曲线中峰电流与扫描速率平方根呈线性关系,确定Fe(Ⅲ)-草酸-葡萄糖酸钙媒介体系电化学反应为受扩散控制的准可逆反应过程。试验得出,组成为C_2H_2O_4 10.08 g/L、Ca(C_6H_(11)O_7)_2 17.92 g/L、Fe_2(SO_4)_3 8 g/L及NaOH 45 g/L的阴极电解液不仅有好的电化学反应性,同时具有最佳的染色性能。The electrochemistry property of the ferric-oxalate-gluconate complex was gold electrode as working electrode. The peak currents of the ferric-oxalate-gluconate co nearly with square root of scanning rate displaying a quasi-reversible cyclic response mp of ex w investigated using a ere found to increase the redox process. Results obtained from the cyclic voltammetry and K/S value can draw the optimal conditions： 8 g/L ferric sulfate, 10.08 g/L oxalate 17.92 g/L calcium gluconate and 45 g/L sodium hydroxide. Under this condition, we can not only get high reducing strength in the electroanalysis process, but also have fabrics with good dyeability
