Ferrous Iron Oxidation

Ferrous iron oxidation is a natural chemical process where iron in its +2 oxidation state (ferrous iron) reacts with oxygen, converting into ferric iron (+3 oxidation state). This transformation occurs in environments like water bodies or soil, often facilitated by bacteria or through chemical reactions. During this process, ferrous iron becomes insoluble and forms reddish-brown particles called iron hydroxides or oxides, which can precipitate out of water. This mechanism is important in natural iron cycling, influence water quality, and is utilized in environmental management and wastewater treatment to remove excess iron.
