Popis:	To degrade the organic compounds in the electroplating wastewater, magnetic field was tentatively introduced into electrocatalytic oxidation on Ti-PbO2 anode. The magnetic field assisted electrocatalytic oxidation can promote anion movement and the generation of active species, resulting more organic compounds to be oxidized and degraded. Oxidation parameters such as treatment time, current density and initial pH of the wastewater were systematically discussed and optimized. The mineralization of organic compounds is improved by over 15% under a magnetic density of 22 mT while the current density is 50 A/m2, pH is 1.8 and the reaction time is 1.5 h. The results indicate that the magnetic field assisted electrocatalytic oxidation has considerable potential in electroplating wastewater treatment.
