“…Advanced oxidation processes (AOPs), generate hydroxyl radicals (HO • ) with an oxidation potential = 2.8 eV, that can react with the several pollutants, oxidizing them to simpler intermediates and potentially to CO 2 and H 2 O [4]. These advanced treatments have already proven their efficiency via different processes, such as TiO 2 heterogeneous photocatalysis [5][6][7][8], electrochemical treatments [9,10], photo-Fenton [3,11] and ozonation [12,13]. The combination of AOPs with UV radiation enhances overall system efficiency, in which light emitting diodes (LEDs) are on the rise compared to traditional mercury vapor lamps.…”
