Background. The use of alternating current in electrochemistry makes it difficult to determine the amount of electricity transmitted through the system. The aim of this work is to develop methods to determine the total amount of electricity flowing through the AC electrochemical system in any form.
Materials and methods. The research was carried out in acidic solutions of zinc plating and nickel plating. The authors used IPC-Pro potentiostat as the source of the pulse current and the current force recorder in time.
Results. The researchers developed the technique of determination of the total amount of electricity at a pulse electrolysis, and the amount of electricity consumed only during the Faraday processes. The work deals with the study of the dependence of the amount of electricity passed through an electrochemical system on the process mode. It is established that the use of reversed mode pulse electrolysis, compared with unipolar mode leads to an increase in the share of current, directed to the recharge of the double electric layer.
Conclusions. The suggested methodologies of determination of the total amount of electricity and the amount of electricity spent on the Faraday processes are universal and allow to calculate the values of substance current output when using polarizing voltage of any form and may be applied for any mode (galvanostatic or potentiostatic).
