• Resumen

  • Data treatment and determination of the standard heterogeneous rate constant of simple ET process (simple electron transfer) & number of electrons consumed in electrode reaction were carried out via convolution-deconvolution voltammetry and digital simulation methods. The working curves required for determination of the standard heterogeneous rate constant, k s, were constructed and discussed. The number of electrons, n, consumed in electrode reaction was calculated via simple method. The electro-reduction of Pb2+ was carried out at hanging mercury drop electrode while the redox behaviour of Fe3+ /Fe2+ couple was performed at glassy carbon electrode to confirm the validity of the reported method in calculation of k s and n in case of simple ET.
