Use of the Saul’yev method for the digital simulation of chronoamperometry and linear sweep voltammetry at the ultramicrodisk electrode

The two-dimensional Saul’yev method of simulating processes at an ultramicrodisk electrode is compared with the fully implicit backward differentiation method started with a few backward implicit steps, and an alternating direction implicit
method. 2D Saul’yev is convenient to program and although it is significantly
slower in execution than the other two methods, it still executes in reasonable
time, and yields equally good results with a suitable choice of discrete intervals,
and despite its inherent propagation problem, and a certain restriction in the
relationship of the spatial and temporal intervals. Saul’yev was implemented for
the diffusion limited potential step experiment, as well as linear sweep
jvoltammetry for a reversible system.
