摘要：

Drops of nitrobenzene and 1,2-dichloroethane with 0.1 M decamethylferrocene (dmfc) are attached to the surface of a paraffin-impregnated graphite electrode and immersed into various aqueous electrolytes. The oxidation of dmfc and the reduction of dmfc(+) cation are enabled by simultaneous transfers of anions between the aqueous electrolyte and the organic solvents. Square-wave voltammetry of this reaction is reported. A linear relationship was observed between the peak potentials of dmfc and the standard Galvani potential differences of the anions. The influence of the anion concentration on this relation is explained. Keywords: Ion transfer; Square-wave voltammetry; Liquid/liquid interface; Nitrobenzene; Ferrocenes; Graphite electrode; Electrochemistry.
