Ferrate(VI) has a molecular formula Fe(VI)O42- in which iron is in a relatively unusual oxidation state, +6. Ferrate(VI) has a strong oxidizing power and it releases a non-toxic by-product, FeIII, which makes it an environmental-friendly oxidant. The oxidation power of ferrate(VI) is useful in removing pollutants in wastewater in seconds with the formation of non-hazardous products. In this paper, we have applied ozonation of FeIII ion in alkaline medium to synthesize ferrate(VI). This is a simple approach to synthesize ferrate(VI). The formation of Fe(VI)O42- ion was confirmed by UV-vis and Mössbauer spectroscopic techniques.
