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

Research output: Contribution to journal/Conference contribution in journal/Contribution to newspaperJournal articleResearchpeer-review

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
voltammetry for a reversible system.
