Sažetak
In voltammetry, results obtained by any differential technique could be presented in the form of a net signal or its components (or both). The latter approach is routinely applied in square wave voltammetry, not only for experimentally obtained current-potential curves, but also for presentation of simulated peaks. It gives a quick insight into the origin of the net signal and makes possible recognition of reversible and irreversible electrode processes. In differential pulse polarography (DPP), however, similar approach is not used, although such a possibility exists in GPES program for obtaining and treatment of experimental data.                                            In order to test the possible applications of current components in DPP (or DPV) as diagnostic tools, several well defined systems, previously studied in our laboratory, were treated in such a way, i.e. new polarograms/voltammograms were recorded (for reversible and irreversible reductions, with and without adsorption) under different conditions and special attention was paid to their “ forward” and “ backward" currents.
