“…In addition, the total amount of iron needed and the sludge generation processes are considerably reduced in the photoFenton system [59]. Consequently, this increases the degradation rate of organic pollutants, such as 4-chlorophenol (4-CP), nitrobenzene (NB), anisole, polychlorinated biphenyls (PCBs) and herbicides [51,60,[62][63][64].…”

Abstract:The basic and applied aspects of Fenton and Fenton-like processes for removal of pollutants using zerovalent iron materials, including nanoparticles, are reviewed in this article. Only those examples including the use of the iron materials together with hydrogen peroxide addition are included. The mechanistic aspects of homogeneous and heterogeneous Fenton processes, still under discussion, are displayed. The use of biogenic generated iron nanoparticles for removal of pollutants is discussed due to their novelty and economy of synthesis.

“…It is well known that the performance of such a complex reactive system depends on the medium's pH [7], with a maximum catalytic activity a pH around 3 [23][24][25][26] From results showed in Figure 2, we could state that maximum COD reduction was obtained at a pH between 2.5 and 3.0. …”

“…The Fenton/photo-Fenton process has been widely reported for the decontamination of a large range of recalcitrant and/or non-biodegradable pollutants during the treatment of industrial wastewaters [11][12][13][14][15][16]. Photo-Fenton studies deal with the process driven by UV or visible light irradiation generating oxidative radicals from Fe 3+ /H 2 O 2 [17][18][19][20][21][22] …”

a b s t r a c tThis study presents the accelerated discoloration/degradation of methylene blue (MB) in solution by Fenton reagent under exposure to ultraviolet (UV) or Vacuum-UV/UV (VUV/UV) light in an innovative micro photo-reactor. The MB degradation was kinetically faster when using VUV/UV light at 254/185 nm compared to UV-irradiation at 254 nm. Oxidative radicals produced by the photo-Fenton process were identified with appropriate scavengers. The addition of benzoquinone (BQ) at millimolar (mM) concentrations to MB solutions precluded completely the MB photo-induced bleaching, while tert-butanol hindered to a lesser extent the MB degradation suggesting that HO 2 • was the predominant intermediate leading to MB degradation. The VUV/UV micro photo-reactor comprised mercury resonance lines at 185 and 254 nm. The photon percentages absorbed by water were estimated to be 16.8% at 254 nm and 78.3% at 185 nm by water, while those absorbed by H 2 O 2 were 0.9% and 2.2%, correspondingly. The solution parameters affecting the features of MB degradation, such as MB, Fe, and H 2 O 2 concentrations, were explored and reaction mechanism was proposed. The lifetimes of • OH and HO 2 • were estimated to be 2 ns and 0.38 s under an optimized solution with 0.016 mM MB, 0.147 mM H 2 O 2 and 0.05 mM Fe 3+ . Moreover, an estimation of the mean free paths of these radicals in solution provided the evidence that it was the radical lifetimes and mean-free paths, not their oxidation potentials that controlled the MB degradation kinetics. This study shows the potential of this VUV/UV assistant photo-Fenton process for the degradation of diluted organic compounds in aqueous solution.
