Fenton's Reaction

Fe2+ + H2O2 → Fe3+ + OH− + OH·

Übersicht

Fenton's reagent generates highly reactive hydroxyl radicals (OH·) from iron(II) and hydrogen peroxide. The hydroxyl radical is one of the strongest oxidizers known, capable of degrading virtually any organic compound. Fe²⁺ is oxidized to Fe³⁺ while H₂O₂ is reduced.

Alltägliches Beispiel

Fenton's chemistry occurs naturally in the body when iron and hydrogen peroxide interact, which is why excess free iron can cause oxidative damage.

Industrielle Bedeutung

Fenton's reagent is used in wastewater treatment to degrade recalcitrant organic pollutants, in soil remediation, and in advanced oxidation processes for water purification.
