摘　　要：用自制的铂超微电极研究了二茂铁(Fc)在咪唑类离子液体中的电化学行为,计算了Fc在离子液体中的扩散系数和粘度系数.结果表明,二茂铁在这些离子液体中均呈现较好的可逆性,测得的扩散系数比用常规电极测得的大,说明超微电极比常规电极有更大的扩散传质速率.Electrochemical behaviors of ferrocene（Fc）in three imidazole ionic liquids are investigated with micro-electrode combination. The diffusion coefficients of Fc in three imidazole ionic liquids and the viscosity of these ionic liquids are estimated. The results of experimental indicate that ferrocene shows a good reversibility in these ionic liquids. The diffusion coefficient that is measured in this paper is larger than that of conventional electrodes. It shows that the mass transfer rate of Ultramicroelectrode is greater than conventional electrodes.
