The various methods for synthesizing Ferrate(VI) were described in detail over 200 years ago. Basically, ferric iron (Fe3+) is oxidized to a high valence (Fe4+ to Fe6+) utilizing; heat, electric power, or an oxidizing chemical. All of these oxidation reactions must take place in a caustic environment, as the synthesized Ferrate is only stable at a high pH. The end product of all of these synthesis procedures is a Ferrate material mixed either with a caustic solution, or other chemicals utilized in the oxidation process. The cost of this Ferrate product is simply the cost of the chemicals or electricity utilized for the oxidation. For example, the unit cost of Ferrate(VI) in these mixtures is inexpensive if commercial feedstocks are utilized (currently around $5.00 per lb. of Ferrate(VI) produced, which translates to approximately $50.00 per million gallons treated at a dose of 1 mg/L FeO42-). If a highly purified Ferrate(VI) product is desired however, the mix must be further processed to separate the Ferrate(VI) from the synthesis solution. This is a tedious (and therefore expensive) process increasing the unit cost of the Ferrate(VI) product by >15X. In summary, if a pure Ferrate(VI) product is required, the cost of it will be prohibitive for large scale environmental use, and cannot compete with other water and wastewater treatment chemicals for similar treatment. In addition, a pure Ferrate(VI) product (powder) is impossible to stabilize, handle, ship, store and apply as a commodity chemical. Essentially all of the research utilizing Ferrate(VI) to date has been done with small quantities of a laboratory-synthesized, pure Ferrate(VI) compound.
