Electrochemical removal of amoxicillin using a Cu doped PbO electrode: Electrode characterization, operational parameters optimization and degradation mechanism.

This work investigated the electrochemical degradation of amoxicillin (AMX) in aqueous solution with Cu-PbO electrode. The main influence factors on the degradation of AMX, such as NaSO concentration, initial AMX concentration, current density and initial pH value, were analyzed in detail. Under the optimal conditions, the removal rates of AMX and chemical oxygen demand (COD) reached 99.
