| Abstract_FL | 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 per-formance 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 pre-cipitation 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 degra-dation 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. |
