Fenton reaction

Fen·ton re·ac·tion

1. the use of H2O2 and ferrous salts (Fenton reagent) to oxidize α-hydroxy acids to α-keto acids or to convert 1,2-glycols to α-hydroxy aldehydes;
2. the formation of OH·, OH-, and Fe3+ from the nonenzymatic reaction of Fe2+ with H2O2; a reaction of importance in the oxidative stress in blood cells and various tissues.

The photo-Fenton process consists in the combination of UV-Vis radiation with the Fenton reaction, proposed by Henry J.
Hydrogen peroxide is then involved in a Fenton reaction and transformed into a hydroxyl radical [13].

In this context, one method of generating the hydroxyl radical is through the Fenton reaction. The Fenton process mechanism is initiated by the formation of the homogeneous hydroxyl radical in accordance with the classical Fenton reaction in acidic medium, as follows [14]:

Because oxygen radicals and hydroxyl radicals can be generated through the Fenton reaction, we asked whether or not exogenous [Fe.sup.+2] (3.003 [micro]mol [FeCl.sub.2]/kg egg) accentuated EtOH-induced (3.025 mmol/kg egg) changes in brain memb rane lipid composition.
The hydroxyl radical-scavenging activity was determined using the Fenton reaction [26], with slight modications.
Espinoza and coworkers [65] reported that the elimination of an diazo dye (acid yellow 42 dye) and its organic intermediates was due to hydroxyl radicals formed both at the anode surface from water oxidation and in bulk solution from Fenton reaction between electrogeneratd [H.sub.2][O.sub.2] and added [Fe.sub.2+].
The second is referred to as the Fenton reaction. Ferrous chloride (FeCl2) is suggested to be effective in the increase of the amount of OH- and OH--like radicals that are efficacious in lipid peroxidation.
