Received Date: 28 April 1997

The diffusion coefficients(D_app) and the heterogeneous electron-transfer rate constants(k_s) for ferrocene in MPEG/salt electrolytes were determined by using steady-state voltammetry.The temperature dependence of the two parameters obeys the Arrhenius equation.The effect of the ionic size of six supporting electrolytes on diffusion and electron transfer dynamics of ferrocene was discussed.
