Fenton and photo-Fenton degradation of 2-chlorophenol: Multivariate analysis and toxicity monitoring

The role of iron on the degradation and mineralization of organic compounds using conventional Fenton and photo-Fenton processes

“…These values have been reported optimal for the treatment of aromatics by Fenton and photo-Fenton processes [11][12][13]16,17,26]. Furthermore, these values of pH and temperature have been widely applied as optimal for the Fenton or photo-Fenton treatment of different substances and wastewaters [11][12][13][14][16][17][18][19][20]22,23,[26][27][28][29]. In order to perform proper comparisons, the same conditions of initial COD and reagents concentrations have been applied in all the treatments.…”

“…Fenton process has been reported to be successful when applied to the treatment of several organic chemicals [10][11][12][13][14][15][16][17][18][19], mainly among the aromatics, and wastewaters like textile dye industry effluent [20], pulp industry effluent [21] and landfill leachate [7,22]. Despite its highly oxidative efficiency and environmental friendly nature, the application of Fenton's reagent to wastewater treatment is limited by the final production of ferric iron sludge, which may add additional waste disposal cost.…”

Synergy Effect in the Combined Photodegradation of an Azo Dye by Titanium dioxide Photocatalysis and Photo-Fenton Oxidation

“…Then we added Fe +2 to monitor decolorization as a result of Photo-Fenton under UVA (Black Light) irradiation. At the moment of Fe 2+ addition (in the dark), the Fenton reaction started (Reactions 3-6) [1,4,16], which led to rapid decolorization of an important percentage…”

Photodegradation of methyl red by advanced and homogeneous photo-Fenton’s processes: A comparative study and kinetic approach

“…4 Advanced oxidation processes involving Fenton's and photo-Fenton's process for the degradation of organic dyes are extensively reported in the literature. [5][6][7][8][9][10] The main advantage of photo-Fenton's process are; reagents are easily available, cheap and cost effective. Further no scattering of light takes place, contact between the pollutants and the catalyst is high since the reaction is homogeneous.…”
