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

Abstract

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.
