Oxidation of TNT by photo-Fenton process

Chemosphere, 2004
A series of photo-Fenton reactions have been performed for the degradation of 2,4,6-trinitrotoluene (TNT) in a 4.2-l reactor. The degradation reaction rate of TNT followed a pseudo-first-order behavior; and the rate constants for 2.4mW cm(-2)UV only, 2.4mW cm(-2)UV/H(2)O(2), Fenton, photo-Fenton (2.4mW cm(-2)) and photo-Fenton (4.7mW cm(-2)) were 0 ...

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 ...

Optimization of photo-Fenton process for the treatment of prednisolone

Environmental Science and Pollution Research, 2018
Prednisolone is a widely prescribed synthetic glucocorticoid and stated to be toxic to a number of non-target aquatic organisms. Its extensive consumption generates environmental concern due to its detection in wastewater samples at concentrations ranged from ng/L to μg/L that requests the application of suitable degradation processes.

Photo‐Fenton and Riboflavin‐photosensitized Processes of the Isoxaflutole Herbicide

Photochemistry and Photobiology, 2018
AbstractThe proherbicide Isoxaflutole (IXF) hydrolyzes spontaneously to diketonitrile (DKN) a phytotoxic compound with herbicidal activity. In this work, the sensitized degradation of IXF using Riboflavin (Rf), a typical environmentally friendly sensitizer, Fenton and photo‐Fenton processes has been studied.

Degradation of bisphenol A by photo-fenton processes

Toxicological & Environmental Chemistry, 2003
The photo-Fenton reactions, which could yield hydroxyl radicals via the catalytic degradation of H2O2 by Fe(II), were focused as one of the abiotic degradation processes of bisphenol A (BPA) in surface waters. At pH 6, in the presence of H2O2 only, 32% of BPA was degraded after 120 min of irradiation. However, 97% of BPA was degraded in the presence of

Effect of Salinity on the Photo-Fenton Process

Industrial & Engineering Chemistry Research, 2007
The existence or presence of diverse hydrocarbons and persistent pollutants in seawater or saline wastewater due to different industrial activities is considerable. The photo-Fenton process is suggested as a possible treatment, but the effect of salinity must be explored.

Polychloroprene degradation by a Photo-Fenton process

Polymer Degradation and Stability, 2005
The influence of iron(III)-chloride-6-hydrate, FeCl3 6H2O on the photodegradation of polychloroprene under different conditions has been investigated. The effects of polymer concentration (Cp), temperature (T ), and polychromatic light exposure (L) on polymer degradation were evaluated using a 2 3 factorial design.

Degradation alternatives for a commercial fungicide in water: biological, photo-Fenton, and coupled biological photo-Fenton processes

Environmental Science and Pollution Research, 2016
Imazalil (IMZ) is a widely used fungicide for the post-harvest treatment of citrus, classified as "likely to be carcinogenic in humans" for EPA, that can be only partially removed by conventional biological treatment. Consequently, specific or combined processes should be applied to prevent its release to the environment.

Degradation kinetics and mechanisms of phenol in photo-Fenton process

Journal of Zhejiang University SCIENCE, 2004
Phenol degradation in photochemically enhanced Fenton process was investigated in this work. UV-VIS spectra of phenol degradation showed the difference between photo-Fenton process and UV/H(2)O(2), which is a typical hydroxyl radical process. A possible pathway diagram for phenol degradation in photo-Fenton process was proposed, and a mathematical ...

Formaldehyde degradation in the presence of methanol by photo-Fenton process

Journal of Environmental Management, 2008
In this study, the photo-Fenton process for the degradation of formaldehyde was investigated in lab-scale experiments. Results showed that methanol, the additive chemical in a commercial product of formaldehyde, was also decomposed during the formaldehyde oxidation reaction. The oxidation reaction was in three-stages. The first stage was the Fe(2+)/H(2)
