Abstract: In order to reduce environmental impact of the organic pollutant N N -dimethylformamide(DMF)emitted byindustrial production,anelectrochemical oxidation method wasemployedforDMFdegradation.Theeffects of four independent factors (current density,pad spacing,pH and initial chloride ion concentration)on DMF degradation were investigated bysingle-factor experiments.The optimal experimental conditions were as follows:the current density was 40mA⋅cm-2 ,the pH was 6,the pad spacing was 2 cm,and the initial chloride mass concentration was 2.34g⋅L-1 .Flow electrolysis was used to optimize and improve the device,and the specific effects of various parameters on the DMFremoval rate were investigated.The results indicate thatthe reaction rate significantly improves with increasing flowcirculation times.When the circulation reaches 3O times,theremoval eficiency of DMF ultimately achieves 93.68% :
