LOVRI, Milivoj. Modeling of Catalytic Reaction in Protein-Film Linear Scan Voltammetry at Rotating Disk Electrode. Port. Electrochim. Acta [online]. 2009, vol.27, n.4, pp.505-515. ISSN 0872-1904.

The numerical method for the simulation of linear scan voltammetry on the rotating disk electrode is adjusted to the problem of irreversible redox reaction between the adsorbed catalyst and the dissolved reactant under transient conditions. The response consists of the wave and the maximum. The peak current depends on the scan rate in linear scan voltammetry, while the limiting current of the wave depends on the rate of rotation of the working electrode. The rate constant of catalytic reaction is determined from the kinetic current under steady-state conditions

Palavras-chave : electro-catalytic reaction; rotating disk electrode; chemical reaction rate constant; linear scan voltammetry; protein-film voltammetry.
