Theory of square wave voltammetry of three step electrode reaction

Simulation of square wave voltammetry of three electrode reactions coupled by two reversible chemical reactions

“…3A is -0.020 V. It corresponds to the single peak responses. This slope can be explained by the theory of EEE mechanism with unstable intermediates [3]: …”

“…The first peak is independent of 2 Y * while the dependence of the second and the third peaks on the logarithm of 2 Y * resembles the relationships of the ECE mechanism. Within a wide range -2 < log( 2 Y * ) < 2 the second peak satisfies the straight These mixed responses can be formed only if the difference between formal potentials is smaller than 0.1 V [3]. If this condition is not satisfied, three peaks appear at all concentrations of the reagent Y -.…”

“…Multistep electrode processes appear in electrochemistry of many organic compounds [1][2][3][4][5][6][7][8][9]. Some of these mechanisms include chemical steps [10][11][12][13][14][15].…”

Recent Advances and Prospects of Square-Wave Voltammetry

“…In general, the advances in the theory of pulse voltammetric techniques, including SWV, can be found in the mini review of Molina et al [40]. Electrode mechanism including three electrode reactions coupled with two chemical reactions (ECECE mechanism) was developed by Lovrić [41], building up on the previous theoretical study of three-step electrode reaction [42]. In [41] three reversible electrode reactions that are connected by two reversible chemical reactions have been considered, with emphasize on the influence of the basic thermodynamic parameters.…”

Simulation of Square Wave Voltammetry of Three Step Redox Reactions on Spherical Electrodes

“…[7][8][9][10][11] These relationships were calculated for chronoamperometry [9,10,[12][13][14][15][16] and voltammetry. [11,[17][18][19][20] They can be used for the determination of kinetic parameters. [10,11,20 -23] In this paper the theory is developed for kinetically controlled three step reaction on spherical electrodes.…”
