Synergetic effects for p-nitrophenol abatement using a combined activated carbon adsorption-electrooxidation process

Abstract: A novel fluidized electrochemical reactor that integrated advanced electrochemical oxidation with activated carbon (AC) fluidization in a single cell was developed to model pollutant p-nitrophenol (PNP) abatement. AC fluidization could enhance COD removal by 22%~30%. In such a combined process, synergetic effects on PNP and COD removal was found, with their removal rate being enhanced by 137.8% and 97.8%, respectively. AC could be electrochemically regenerated and reused, indicating the combined process would be promising for treatment of biorefractory organic pollutants.

Key words: Electrochemical reactor, p-nitrophenol, Activated carbon fluidization, Wastewater treatment, Synergetic effect
