Abstract

The electro-generation of H2O2 and the abatement of the model organic pollutant Acid Orange 7 (AO7) inwater by an electro-Fenton process were performed both in a conventional undivided macro cell and, forthe first time, in a microfluidic reactor. Under optimized operative conditions, the reduction of oxygen inthe microdevice gave rise, using graphite cathode, to a concentration of H2O2 of about 6 mM, one order ofmagnitude higher than that achieved in conventional cells. Similarly, when electro-Fenton was performedin the microfluidic reactor a dramatic increase of the abatement of COD was achieved with respect to thatobtained in a conventional cell.
