Fenton's Reaction

Fe2+ + H2O2 → Fe3+ + OH− + OH·

概要

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.

日常の例

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