Potassium ferrate is the chemical compound with the formula K2FeO4. This purple salt is paramagnetic and is a rare example of an iron(VI) compound. In most of its compounds iron has the oxidation state +2 or +3 (Fe2+ or Fe3+). Reflecting its high oxidation state FeO42โ is a powerful oxidizing agent.K2FeO4 has attracted interest for applications in green chemistry because the by-products of its use iron oxides are environmentally innocuous.
