Numerical simulation of voltammetry focusing on the effect of initial concentration of products in reversible systems with complex stoichiometry _1

摘要

The effect of initial concentration of products in a general reaction of reversible process with complex stoichiometry expressed as mO + ne - →qR was evaluated using numerical simulations with various complex stoichiometric coefficients m and q of oxidized (O) and reduced (R) species, respectively, and with various initial concentrations. In the simulations, the transform of voltammograms according to changes in the initial concentrations were characterized by the parameter γφ (= C~* O (DO)~(1/2)/C~* R (DR)~(1/2)) for any stoichi- ometric system. Based on the simulation results, empirical relations were obtained for (1) peak potential involving parameters for stoichiometry (m and q) and for the initial conditions (γφs), and (2) peak current.
