“…Fe(0) + 2H + + O2 → Fe(II) + H2O2 (6) Fe(0) + 2H + + H2O2 → Fe(II) + 2H2O (7) In addition to H + and O2, other species may also act as ultimate electron acceptors. Depending on the composition of the aqueous phase, these species may include Cr(VI), NO3 -, H2O2, Fe(III), nitrocompounds, azo-compounds and even H2O [12,15].…”

“…These results may be explained by taking into account that, in acidic media, highly reactive and rather unselective HO  radicals are produced through the Fenton reaction in the presence of added H2O2 (Eq 1). In general, HO  radicals may react by abstraction of hydrogen atoms, addition to unsaturated bonds or direct electron transfer reactions [7]. In the case of azo dyes, HO  radicals participate in addition reactions that trigger the oxidation of either azo linkages or aromatic structures.…”

“…Estas incluyen el uso de ultrasonido (Sono-Fenton), la aplicación de un potencial eléctrico (Electro-Fenton) y la irradiación con luz visible/UV cercano (Foto-Fenton). Esta última estrategia es la más estudiada debido a la posibilidad de usar la luz solar como fuente de irradiación [22]. En estas circunstancias, la irradiación genera una nueva fuente de Fe(II) y radicales OH • : Fe(III) + hv + OH - Fe(II) + HO •…”

“…Ninguno de estos trabajos acoplando un sistema ZVI con un proceso Fenton fue realizado en presencia irradiación con luz UV/Visible (Foto-Fenton), la cual es una alternativa interesante frente a la posibilidad de poder reemplazarla en un futuro por radiación solar. Esta estrategia ha demostrado muy buenos resultados para la degradación de procesos tipo-Fenton en batch, llegándose incluso a construirse plantas de tratamiento que utilizan radiación solar [22].…”
