Advanced oxidation processes such as Fenton reagent generates highly reactive hydroxyl free radicals to oxidize various compounds in the water and wastewater. The efficiency of different Fenton-related oxidative processes such as Fenton, solar-Fenton, UV-Fenton and Fenton reactions in different batch reactors was examined using benzene as pollutant in aqueous solutions. A batch study was conduc...

Various aspects of the participation of Fenton chemistry in biology and medicine are reviewed. Accumulated evidence shows that both hydroxyl radical and ferryl [Fe(IV)=O]2+ can be formed under a variety of Fenton and Fenton-like reactions. Some examples of metal-independent hydroxyl radical production are included. Extracellular Fenton reaction is illustrated by the white rot and brown rot wood...

diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. it was related to toxicity for aquatic organisms, animals, and humans. waters contaminated with such persistent insecticides should be treated with suitable treatment processes. in this research, diazinon removal from aqueous solutions by the photo–fenton–like process (uv/h2o2/fe0) was investigated. this e...

Munitions wastes such as TNT are widespread contaminants in soils and ground waters. We investigated a coupled abiotic-biotic treatment scheme for remediation of aqueous solutions of TNT. Mineralization of aqueous TNT (0.22 mM) was initially optimized with minimum reactant use (Fe3+ and H2O2) in light-assisted and dark, modified Fenton reactions at acidic and neutral pH. Complete TNT degradatio...

magnetite (feo.fe2o3) nanoparticles immobilized on silica and modified by treatment apolaccase were used to decolorize the industrial wastewater from basic red 9 (br9 by way of fenton and fenton-like processes. the surface changes to the silica were determined by scanning electron microscopy, fourier transform infrared spectroscopy, x-ray diffraction and energy-dispersive x-ray spectroscopy. th...

A composite of nano-zerovalent iron (nZVI) supported on granular activated carbon (GAC) was synthesizedthrough adsorption-reduction method, and its performances used as catalyst of Fenton-like were investigated to degrade methylene blue (MB) in model wastewater.Theresults show thathomogeneous dispersion of nZVI was greatly improved after supported on GAC. In comparison, the composite (nZVI/GAC)...

Abstract. Various remediation technologies are being developed for the destruction of groundwater pollutants like ...

Oxidation of pollutants in waste water by photo-Fenton reaction has proven an ecofriendly and economical method. Oxidation of amido black – 10B, (an acid dye of azo series) using photoFenton reagent was investigated under ambient conditions. The effect of different parameters like the concentration of ferric ion, amido black10B and hydrogen peroxide, pH, light intensity etc. on the reaction rat...
