Calculation of Electrochemical Parameters Starting from the Polarization Curves of Ferrocene at Glassy Carbon Electrode

This work is a contribution to the calculation of electrochemical parameters from the polarization curves of ferrocene. The parameters are: 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 half-wave potentials (E_1/2) of the couple in the investigated solvents have been evaluated. The diffusion coefficients (D) have been calculated using the Randles-Sevcik equation.
