What can electrochemical test do in anodic oxidation wastewater treatment?

Electrochemical characterization is essential in connecting electrodes' degradation and intrinsic properties. Currently, the application of electrochemical characterization in the field of anodic oxidation (AO) for wastewater treatment mainly focuses on the qualitative comparison of catalytic activity and the stability of electrodes. Meanwhile, the effect of the reaction environment and the need for horizontal comparison should pay attention. The common electrochemical indexes in the field of AO obtained from cyclic voltammetry, linear sweep voltammetry, electrochemical impedance spectroscopy, and other electrochemical methods should be tested more carefully according to the requirements of AO. The variation of the indexes before and after the degradation process is desirable for monitoring and forecasting the system performance.
