POLYNOMIAL METHOD FOR CALCULATION OF ELECTROKINETIC PARAMETERS IN A CONTROLLED CHARGE-TRANSFER SYSTEM

Guzman, M.; Ortega, P.; Vera L.

Abstract

A method is presented for the calculation of electrokinetic parameters of a controlled electrochemical reaction employing only charge-transfer. The method includes development of a polynomial expression of the Butler-Volmer equation from which constants were obtained, which were then used to determine adequate relations for the calculation of electrokinetic parameters. This method can be used with polarization data obtained by potentiostatic or galvanostatic techniques. Calculations carried out with synthetic and experimental data showed that the calculation method was precise and uncomplicated to use. The method is limited in that it is unable to make use of the null data pair 0,0 .
