Several homogeneous photo-based advanced oxidation processes-namely photolysis, photo-oxidation, and photo-Fenton oxidation—were investigated for the elimination of ibuprofen in water. The effects several operating parameters, such as lamp type (low or medium pressure mercury, xenon-arc), concentration hydrogen peroxide (0.5 to 7 times stoichiometric amount required mineralization), Fenton reag...

Many types of advanced oxidation processes (AOPs), namely Fenton (Fe 2+ /H2O2) with different doses, Fenton-like (UV/Fe 2+ /H2O2), photo-Fenton (Fe 2+ /H2O2/TiO2), and plasma technology have been investigated for the removal of organic matters (COD content) from landfill leachate. Fenton's oxidation was the most effective as the most effective ratio 1/10 (Fe 2+ /H2O2) which allow the COD remova...

this study deals with employing foundry sand (fs) as new low cost iron source in heterogeneousphoto-fenton process for the degradation of herbicide isoproturon (ipu) in aqueous solution. thecharacterization of the fs by eds confirmed presence of iron (23%) required for photo-fenton andsimultaneously confirmed absence of any heavy metals which may be susceptible to leaching. the photo-fenton eff...

Several advanced oxidation processes such as hydrogen peroxide photolysis, the Fenton treatment, photo-Fenton treatment, and ozonation combined with hydrogen peroxide and UVradiation for the destruction of 2,4-dinitrophenol were studied. Advanced oxidation processes, especially the Fenton treatment, were found to be effective for the degradation of 2,4-dinitrophenol and removal of toxicity. Acc...

the efficiency of oxidation processes, enzymatic treatment, and combined enzymatic/chemical sequences on color remediation of cmp pulp mill effluent was investigated. two kinds of fungal enzymes; laccase (ec: 1.10.3.2) from terametes versicolor and versatile peroxidase (ec: 1.11.1.7) from bjerkandera adusta were chosen and applied. also, the effect of external mediator on the enzyme based degra...

Solar assisted Photo Fenton was compared with advanced oxidation processes for their color and COD removal efficiency and cost effectiveness. H2O2 alone appeared to be inefficient to reduce color and COD content of any effluent. The performance of Fenton process was slightly better, color and COD removals were 45 % and 63% respectively. Photo Fenton treatment of blue effluent resulted into colo...

This research investigated the efficiency of Advanced Oxidation Processes, Enzymatic treatment, and combined enzymatic/AOPs sequences on color remediation of CMP pulp and paper mills effluent. Regarding enzymatic treatment two kinds of fungal enzymes; Laccase (EC: 1.10.3.2) from Terametes Versicolor and Versatile Peroxidase (EC: 1.11.1.7) from Bjerkandera adusta were chosen and applied. Also, t...

The application of the photo-Fenton process for the treatment of wastewaters contaminated with diesel oil was investigated. This particular process has been widely studied for the photochemical degradation of highly toxic organic pollutants. Experiments were performed according to a factorial experimental design at two levels and two variables: H(2)O(2) concentration (5-200 mM) and Fe(2+) conce...
