“…Malato et al [11] have successfully tested peroxodisulfate (S 2 O 8 2− ) and oxone (2KHSO 5 ·KHSO 4 ·K 2 SO 4 ) which is essentially HSO 5 − and also known as peroxomonosulfate (PMS). This oxidant has been used in the degradation of pentachlorophenol under visible light irradiation in conjunction with a TiO 2 oxidant as an alternative to H 2 O 2 which is widely used for this purpose.…”

“…AOT's [10][11][12] uses UV-Vis light to activate the degradation of many organic compounds through the formation of metallo-complexes like: ligand to metal (LMCT), metal to ligand or ligand to ligand (LLCT) charge transfer photo-dissociation states leading to a variety of radicals under light irradiation [6][7][8][9][10]21,23,24]. Ozone has also been used as a source of oxidative radicals in waste water treatment [2].…”

“…The use of inorganic oxidizing species has been demonstrated to enhance the rates of degradation of different organic contaminants remarkably because they trap the photogenerated electrons more efficiently than O 2 [34]. For better results, these additives should fulfill the following criteria: dissociate into harmless by-products and lead to the formation of OH or other oxidizing agents [35].…”

“…For example, the For sodium persulfate, the product SO 4 ÿ is a very strong oxidant (E 0 ¼ 2.6 eV) and engages in at least three reaction modes with organic compounds: by abstracting a hydrogen atom from saturated carbon, by adding to unsaturated or aromatic carbon, and by removing one electron from carboxylate anions and from certain neutral molecules [34]. For Fe(NO 3 ) 3 , Fe(OH) 2þ , the Fe 3þ -hydroxyl species predominant in aqueous solutions in the pH range 2.5e5.5, is the most photoactive Fe 3þ species in the 300e400 nm range.…”
