Bk. Jin et al., APPLICATION OF THE FINITE ANALYTICAL NUMERICAL-METHOD .3. DIGITAL-SIMULATION OF CHARGE-TRANSFER TO A MICRO-RING ELECTRODE INTERFACE, Journal of electroanalytical chemistry [1992], 417(1-2), 1996, pp. 45-51
The finite analytical numerical method (FAM) combined with a conformal
map has been used to study diffusion problems at a micro-ring electro
de. The chronoamperometric and voltammetric responses for both reversi
ble and quasi-reversible charge transfer at ring microelectrodes of di
fferent thicknesses are simulated, The effect of the thickness of the
micro-ring electrode, the potential sweep rate and the heterogeneous e
lectron transfer kinetic parameter on the voltammetric responses is di
scussed. The results show that the thin micro-ring electrode is more a
ppropriate for the evaluation of fast electrode reaction rate constant
s than a thick micro-ring or microdisk electrode.
