This work assessed the effectiveness of several methods on degradation of microcystin-LR (MC-LR) by different Advanced Oxidation Processes, like solar photo-Fenton, UV-A/photo-Fenton and UV-C/H2O2. UV-C/H2O2 and UV-A/photo-Fenton processes were carried out in a bench scale photochemical apparatus and the solar photo-Fenton treatment was performed in a ...

Response Surface Analysis of Photo‐Fenton Oxidation of Simazine
Water Environment Research, 2009Removal of simazine from aqueous solution by photo‐Fenton oxidation was investigated using Box‐Behnken statistical experiment design and the response surface analysis. The effects of simazine, hydrogen peroxide (H2O2), and iron(II) concentrations on the extent of simazine and total organic carbon (TOC) removals were investigated.

Photo‐Fenton and Riboflavin‐photosensitized Processes of the Isoxaflutole Herbicide
Photochemistry and Photobiology, 2018AbstractThe 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.

Abstract A comparative study between the visible light induced photo-Fenton system (light/Fe 2+ /H 2 O 2 , P-F) and photo-Fenton like system (light/Fe 2+ /S 2 O 8 2− , P-FL) was carried out for the degradation of antibiotic sulfamethazine (SMZ). It was found that white-LED light could enhance the SMZ degradation in both photochemical systems.

Degradation of bisphenol A by photo-fenton processes
Toxicological & Environmental Chemistry, 2003The 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, 2007The 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.

Fe-Mofs Nanosheets for Photo-Fenton Degradation of Carbamazepine
ChemosphereIron(II)-based metal organic framework (Fe(II)-MOF) nanosheets have emerged as promising candidates for photo-Fenton catalysis. However, efficiently synthesizing Fe(II)-MOF nanosheets remains a significant challenge. Here, a bottom-up synthesis strategy is proposed to prepare two-dimensional Fe-MOF nanosheets (TFMN) with micrometer lateral dimensions ...

Optimization of a photo-fenton prototype reactor
Chemosphere, 1999Abstract A prototype reactor for the Photo-Fenton method was applied for highly contaminated wastewaters up to a TOC of 1400 ppm and COD of 12000 mg/L. The influences of different light sources, iron concentrations and two glass sorts on the degradation rate of 4-Chlorophenol have been studied.

Polychloroprene degradation by a Photo-Fenton process
Polymer Degradation and Stability, 2005The 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.
