A simple and efficient approach for simulation of adsorbed species in the diffusionless case: A new look on chronoamperometry data

Abstract

In this work the electrochemical response of adsorbed species without mass-transport effects was revisited. Finite difference formulas were tested for simulation of current versus potential even considering lateral interactions between adsorbates. This approach was significantly simpler than others present in the literature. Excellent results were observed for cyclic voltammetry and chronoamperometry in any kinetics range. Exact solutions for chronoamperometry were tested using multiple-pulsed simulated data. More than one path was pointed out to determine the kinetic parameters involved such as E°’_ads, n, α and k_s.
