The presence of estrogens in livestock excrement has raised concerns about their potential negative influence on animals and the overall food cycle. This is the first investigation to simultaneously remove estrogens, including estriol (E3), bisphenol A (BPA), diethylstilbestrol (DES), estradiol (E2), and ethinyl estradiol (EE2), from cow manure using a Fenton oxidation technique. Based on the r...

Fenton-like system had long been modified to promote its adaptability and efficiency by adding extra components like metal chelators or reducers. Nonetheless, chelator such as ethylene diamine tetraacetic acid (EDTA) was harmful in high dosage. While strong reducers could efficiently the generation speed of hydroxyl radicals (HO), they also get oxidized easily during storage time, for which fur...

The fate of hydrogen peroxide in a model wine system was studied under a competitive scenario in the presence of ferrous ions and sulfur dioxide. The metal-catalyzed reduction of hydrogen peroxide (H(2)O(2)), referred to as the Fenton reaction, yields hydroxyl radicals capable of oxidizing ethanol to acetaldehyde and is now thought to be a key step in nonenzymatic wine oxidation. It appears tha...

The stability of the coffee flavor compound furfuryl mercaptan has been investigated in aqueous solutions under Fenton-type reaction conditions. The impact of hydrogen peroxide, iron, ascorbic acid, and ethylenediaminetetraacetic acid was studied in various combinations of reagents and temperature. Furfuryl mercaptan reacts readily under Fenton-type reaction conditions, leading to up to 90% deg...

the heterogeneous photo-fenton degradation of crystal violet under visible light has been investigated usingcopper modified iron oxide. the photocatalyst has been prepared by coprecipitation method. the rate ofphotocatalyic degradation of dye was monitored spectrophotometrically. it has been observed thatphotocatalytic degradation follows pseudo first order kinetics. the effect of various param...

Maillard reaction products were prepared by heating xylose and lysine at pH 9.0 and 100°C for 3 h, and then fractionated by ethyl ether and ethanol into acidic, neutral and basic low-molecular-weight, ethanol-soluble and ethanol-insoluble fractions. The ethanol-soluble and -insoluble fractions were the major fractions of the xylose-lysine Maillard reaction products (XL MRPs), contributing 79.5%...

Iron and copper toxicity has been presumed to involve the formation of hydroxyl radical ( . OH) from H2O2 in the Fenton reaction. The aim of this study was to verify that Fe 2+ -O2 and Cu + -O2 chemistry is capable of generating . OH in the quasi physiological environment of Krebs-Henseleit buffer (KH), and to compare the ability of the Fe 2+ -O2 system and of the Fenton system (Fe 2+ + H2O2) t...
