Fenton's Reagent is the mixture of Fe(II) and hydrogen peroxide.

It is mainly used to convert benzene to phenol directly.

tell me whether i am correct or not?

reply is must.

Many metals have special oxygen transfer properties which improve the utility of hydrogen peroxide. By far, the most common of these is iron which, when used in the prescribed manner, results in the generation of highly reactive hydroxyl radicals (OH).........!!!!!

The reactivity of this system was first observed in 1894 by its inventor H.J.H. Fenton(loooong name :):) ), but its utility was not recognized until the 1930’s once the mechanisms were identified.

aaj kal...... Fenton’s Reagent is used to treat a variety of industrial wastes containing a range of toxic organic compounds (phenols, formaldehyde, BTEX, and complex wastes derived from dyestuffs, pesticides, wood preservatives, plastics additives, and rubber chemicals).

The process may be applied to wastewaters, sludges, or contaminated soils, with the effects being:

• Organic pollutant destruction







•  


• Toxicity reduction







•  


• Biodegradability improvement







•  


• BOD / COD removal


• Odor and color removal

hi

above definations are correct ..

It was developed in the 1890s by Henry John Horstman Fenton.

Ferrous Iron(II) is oxidized by hydrogen peroxide to ferric iron(III), a hydroxyl radical and a hydroxyl anion.

Iron(III) is then reduced back to iron(II), a peroxide radical and a proton by the same hydrogen peroxide (disproportionation).

(1) Fe²⁺ + H₂O₂ → Fe³⁺ + OH· + OH⁻

(2) Fe³⁺ + H₂O₂ → Fe²⁺ + OOH· + H^{+                                     !!!!!!}
