Abstract: To investigate the electrocatalytic degradation effect of anthracene in coking wastewater, Ti/PbO₂, Ti/PANI/PbO₂ and Ti/PANI/PbO₂-Ce electrodes were prepared by electrodeposition, and the electrodes were subjected to scanning electron microscopy and X-ray diffraction characterization, electrochemical performance test, hydroxyl radical (·OH) production capacity test and accelerated lifetime test.The results showed that the Ti/PANI/PbO₂-Ce electrode modified with polyaniline (PANI) and cerium (Ce) had better surface morphology and higher catalytic activity, and could produce more ·OH with an oxygen precipitation potential of 1.83 V and an accelerated lifetime of 720 min.The Ti/PANI/PbO₂-Ce electrode was used for the degradation of anthracene in coking wastewater, and the effects of the main factors on the degradation effect were investigated, and the optimal degradation conditions for anthracene were obtained as voltage 14 V, plate spacing of 1.0 cm, electrolyte concentration of 0.35 mol/L, reaction time of 120 min, pH value of 10.The Ti/PANI/PbO₂-Ce electrode showed good electrocatalytic performance.
