Electrode polarization refers to the formation of an oxide film or other covering layer on the electrode surface due to chemical or electrochemical reactions when the electrode is in contact with the fluid, which will cause changes in the electrode potential and affect the accuracy of the measurement. Passivation treatment usually involves chemical or electrochemical methods, the purpose of which is to form a stable protective film on the electrode surface, which can prevent or slow down further chemical reactions, thereby reducing electrode polarization.

[0003] At present, electrode passivation equipment usually adopts fixed stations and manual operation to carry out the passivation process of electrodes, including degreasing, cleaning, passivation, re-cleaning, neutralization and final rinsing.
