In the present work the oxidation of ferrocene, , to the ferrocenium cation, , was examined in the solvents dichloromethane, and aqueous ethanol using the technique of cyclic voltammetry. The anodic (E_pa) and the cathodic (E_pc) peak potentials, as well as the corresponding anodic (i_pa) and cathodic (i_pc) peak currents, were obtained at different scan rates (0.05, 0.10, 0.30, 0.50 V.s^-1). The diffusion coefficients (D) have been calculated using the Randles-Sevcik equation. The effects of changing the scan rate on the electrochemical behavior of ferrocene have been examined.
