Comparison of Fenton and sono-Fenton bisphenol A degradation

Journal of Hazardous Materials, 2007
Degradation of bisphenol A (BPA) was carried out with the Fenton reagent with and without additional sonochemical treatment. The Fenton and the sono-Fenton decomposition of BPA showed that ultrasound irradiation of wastewater improved the wet oxidation process of 25 mg l(-1) BPA solutions.

Oxidation of explosives by Fenton and photo-Fenton processes

Water Research, 2003
In this study, the Fenton process was used to explore the possibility of treating explosives, namely 2,4,6-trinitrophenol (PA), ammonium picronitrate (AP), 2,4-dinitrotoluene (DNT), methyl-2,4,6-trinitrophenylnitramine (Tetryl) and 2,4,6-Trinitrotoluene (TNT), hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7 ...

Effect of pH on Fenton and Fenton‐like oxidation

Environmental Technology, 2009
The lifetime of H2O2 is an important factor in the feasibility of Fenton's reaction for soil and groundwater remediation. The lifetime of H2O2 was evaluated in Fenton's reaction and Fenton-like reactions with haematite and magnetite. H2O2 was more stable in the Fenton-like reaction than in the Fenton's reaction.

Comparison of o-toluidine degradation by Fenton, electro-Fenton and photoelectro-Fenton processes

Journal of Hazardous Materials, 2011
A Box-Behnken design (BBD) statistical experimental design was used to investigate the degradation of o-toluidine by the electro-Fenton process. This method can be used to determine the optimal conditions in multivariable systems. Fe(2+) concentration (0.2-1.0mM), H(2)O(2) concentration (1-5mM), pH (2-4), and current (1-4A) were selected as independent

Trends in the use of Fenton, electro-Fenton and photo-Fenton for the treatment of landfill leachate

Waste Management, 2010
Advanced oxidation processes (AOPs) such as Fenton, electro-Fenton and photo-Fenton have been applied effectively to remove refractory organics from landfill leachate. The Fenton reaction is based on the addition of hydrogen peroxide to the wastewater or leachate in the presence of ferrous salt as a catalyst.

Mineralization of Metoprolol by Electro-Fenton and Photoelectro-Fenton Processes

The Journal of Physical Chemistry A, 2011
Solutions of about 0.25 mM of the β-blocker metoprolol tartrate (100 mg L(-1) total organic carbon) with 0.5 mM Fe(2+) in the presence and absence of 0.1 mM Cu(2+) of pH 3.0 have been comparatively degraded under electro-Fenton (EF) and photoelectro-Fenton (PEF) conditions.

Replacement of H2O2 by O2 in Fenton and photo-Fenton reactions

Chemosphere, 2000
The consumption of oxygen during the degradation of aniline by Fenton and photo-Fenton reactions is studied. The effect that parameters like aniline, Fe(II) and H2O2 initial concentration, pH, temperature and O2 flow rate have on the ratio O2 consumed/H2O2 consumed is examined.

Kinetics of aniline degradation by Fenton and electro-Fenton processes

Water Research, 2006
Aniline degradation at pH 2 by Fenton and electro-Fenton processes was kinetically investigated in this study. Electro-Fenton process was found to be superior to ordinary Fenton process with the current impacts of 1.2 to 3.1 for removal efficiency and 1.2 to 5.8 for degradation rate depending on initial Fe2+ concentration.

MINERALIZATION OF HERBICIDES IMAZAPYR AND IMAZAQUIN IN AQUEOUS MEDIUM BY, FENTON, PHOTO‐FENTON AND ELECTRO‐FENTON PROCESSES

Environmental Technology, 2008
Oxidative degradation of aqueous solutions of imazapyr and imazaquin herbicides at room temperature and pH 3.0 has been investigated by Fenton, photo-Fenton and electro-Fenton processes. The high degradation power of these advanced oxidation processes is due to the large production of hydroxyl radicals (*OH), a strong oxidizing agent, by reaction ...

Modelling Approach to Fenton and Photo-Fenton Treatments

Journal of Advanced Oxidation Technologies, 2008
AbstractFenton, Fenton-Like and Photo-Fenton processes were revealed effective in the mineralization of 4-chlorophenol, 4-CP. Experiments for the Fenton photo-assisted degradation of 4-CP were planned under the Design of Experiments (DOE) scheme.
