REVERSAL COULOSTATIC STUDY OF THE OXYGEN ELECTROREDUCTION IN CARBONATE MELTS - THEORY

An original, relaxation coulostatic method is developed for studying e lectrode processes when switching from a steady state. In contrast to the conventional coulostatic method, in the method put forward, the st udied electrode is initially not in equilibrium but in a steady state. The concentration of the electroactive component is preset not in the solution bulk but in a thin layer near the electrode, using an anodic or cathodic current. The apparent reaction order can be easily determ ined by one short experiment, from the dependence of the exchange curr ent on the steady-state current value.
