A network approach has been used for the simulation of cyclic voltammetry. A general network model which is applicable for reversible and irreversible electron transfer of a freely diffusing species, coupled with a preceding or following chemical reaction, has been used to obtain the corresponding cyclic voltammograms from numerical simulations by means of the computer program PSPICE. The calculated voltammograms are in very good agreement with those reported in the literature. This approach allows one to solve problems of great mathematical complexity by an efficient graphical method, using personal computers and a moderate cost in computer time.
