Cyclic voltammetry of the second order CE mechanism at the thin mercury film covered stationary planar electrode

摘要

A theoretical model of electrode reaction influenced by the kinetics of complex formation and dissociation is developed for cyclic voltammetry. It is assumed that the electro-reductions of free metal ions and the complex are reversible and totally irreversible, respectively, and that the ligand is not present in great excess. The results show that the stripping peak current and potential depend on the relative bulk concentration of ligand, particularly within the range 1 3, and on the rate constant of complex formation.
