Potassium ferrate(cas 39469-86-8) 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, FeO42&minus; is a powerful oxidizing agent.It has been employed in waste-water treatment as an oxidant for organic contaminants and as a biocide.</p>
