Degradation of atrazine by Fenton and modified Fenton reactions
Monatshefte für Chemie - Chemical Monthly, 2011For 50 years, farmers around the world have relied on the herbicide atrazine—one of the triazine family of herbicides—to fight weeds in corn, grain sorghum, sugar cane, and other crops. Although prohibited in the European Union because of widespread contamination of waterways and drinking water supplies, it is still one of the most widely used ...

Activity Regulation of Fenton/Fenton‐like Reactions in Single‐Atom Catalysis
ChemCatChem, 2023AbstractOn the one hand, Fenton‐like reactions are common side reactions in electrocatalytic oxygen reduction reaction (ORR). The generated reactive oxygen species (ROS) could damage the active sites of single‐atom catalysts (SACs), thereby affecting the stability of the catalysts.

Replacement of H2O2 by O2 in Fenton and photo-Fenton reactions
Chemosphere, 2000The 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.

Identification and application of Phyto-Fenton reactions
Chemosphere, 2016The formation of hydroxyl radicals (•OHs) by aquatic plants was investigated using electron-spin-resonance (ESR) spectroscopy and fluorescence microscopy. ESR observations, using 5- (diethoxyphosphoryl)-5-methyl-pyrroline N-oxide as a trapping agent, indicated that the signals produced by aquatic plants ground with ferrous iron ions are almost ...

Photo-Fenton Reaction at Near Neutral pH
Environmental Science & Technology, 2009The photo-Fenton reaction, oxidation of photoproduced ferrous iron by hydrogen peroxide, produces reactive oxidants that may be important to degradation of biologically and chemically recalcitrant organic compounds in surface waters at circum-neutral pH. Sufficient Fe(II) for the photo-Fenton reaction was produced in situ at two field sites (pH 6.1-7.1)

Cancer Treatment through Nanoparticle-Facilitated Fenton Reaction
ACS Nano, 2018Currently, cancer is the second largest cause of death worldwide and has reached critical levels. In spite of all the efforts, common treatments including chemotherapy, photodynamic therapy, and photothermal therapy suffer from various problems which limit their efficiency and performance.

New Mechanistic Aspects of the Fenton Reaction
Chemistry – A European Journal, 2009AbstractThe kinetics of the Fenton reaction was studied in detail. A second reaction step in the presence of excess H2O2 is attributed to formation of the complex FeIII(−O2H)aq. Therefore, the reaction of Fe(H2O)62+ with FeIII(−O2H)aq in the presence of FeII to form FeIIIaq (k=(7.7±1.5)×105 M−1 s−1) may contribute to the overall Fenton reaction, and ...

Reactions in Water: Alkyl Nitrile Coupling Reactions Using Fenton’s Reagent
The Journal of Organic Chemistry, 2008The coupling reaction of water-soluble alkyl nitriles using Fenton's reagent (Fe(II) and H2O2) is described. The best metal for the reaction is iron(II), and the greatest yields are obtained when the concentration of the metal is kept low. Hydrogen-atom abstraction is selective, preferentially producing the radical alpha to the nitrile.
