COMPUTER-SIMULATION OF A SQUARE SCHEME WITH REVERSIBLE AND IRREVERSIBLE CHARGE-TRANSFER BY THE NETWORK METHOD

Digital simulation of the square scheme in cyclic voltammetry has been carried out by the network method. A network model for this mechanism , with or without cross-reaction and with reversible or irreversible c harge transfer, is proposed. Results obtained using uniform or quasi-u niform grids are compared with those obtained by other methods using e xponential grids. It is shown that the network method is accurate and efficient over all kinetic domains of interest, without increases in C PU time, and it is not necessary to consider either numerical- or prog ramming aspects. The influence of the second-order cross-reaction on t he cyclic voltammograms has also been examined for reversible and irre versible charge transfers.
