Elimination voltammetry as an innovative tool of electroanalysis

The review presents the application potential of elimination voltammetry with linear scan (EVLS) in the electroanalysis of organic and inorganic electroactive substances. This innovative method can be considered a software tool that transforms the total current-voltage records measured at different scan rates into elimination functions providing new useful information about a given electrode process. Some EVLS functions are capable of separating overlapped voltammetric signals, identifying the adsorbed state of the analyze, and detecting the preceding chemical reaction before the electron transfer. EVLS finds use in solving the mechanisms of electrode processes and determining significant physicochemical parameters, such as charge transfer coefficients and electrochemical equilibrium protonation constants. This review selects and draws attention to certain problems that may accompany EVLS in voltammetric experiments on solid electrodes.

Automated summary

EVLS is an innovative method in electroanalysis that can transform current-voltage records into elimination functions to provide new information and solve mechanisms in electrode processes. In addition to separating overlapped voltammetric signals and identifying the state of the analyte, EVLS can also detect chemical reactions and determine physicochemical parameters.
