Stabilized Ferrates (VI): Synthesis Method and Applications

Iron (VI) ion FeO 4 2- possesses properties which make it potentially useful in certain areas of water purification as an oxidizing, coagulant, flocculant and bactericidal agent. Due to its high instability, ferrate (VI) has not been extensively produced and studied. In this paper, we recommend a synthesis method of alkali and alkaline-earth stable ferrates which can be easily produced industrially; these stable ferrates are characterized by the formula M (Fe, X)O4. Applications of these compounds, in particular K2(Fe, S)O4, in water treatment have been investigated.
