The voltammetric method of analysis introduces rigid requirements to the surface of the working electrode, the state of which directly depends on the reproducibility of the results of the analysis. Nowadays there are popular methods of studying surface morphology, such as AFM, SEM. These methods require highly qualified personnel and expensive equipment. An alternative to surface research is the spectroscopy of electrochemical impedance.

Electrochemical impedance spectroscopy is a highly sensitive method that makes it possible to evaluate the state of the electrode surface in the form of simple equivalent electrical circuits.
