Study of multistep electrode processes in triple potential step techniques at spherical electrodes

In this paper, a reversible multistep electrode process is studied by the most popular triple pulse techniques as Reverse Differential Pulse Voltammetry and Double Differential Pulse Voltammetry. The equations presented here are valid for spherical electrodes of any size (including planar and ultramicrospherical electrodes as limit cases) and can be used to describe the electrochemical behaviour of molecules with multiple redox centers, whether they are interacting or not. The comparison between results in triple and double pulse techniques for reversible multistep processes allows us to draw important conclusions regarding the suitability of such techniques and the characterization of reversible processes.
