Formation of iron(VI) in ozonalysis of iron(III) in alkaline solution
摘要:
Here we report the formation of iron in hexavalent state, (FeO42-)-O-VI in ozonalysis of iron(III) in alkaline medium. The formation of tetrahedral (FeO42-)-O-VI ion is confirmed by UV-Visible and Mossbauer spectroscopic techniques. The value of isomer shift, delta, of the tetraoxy anion is consistent with known 6 values for various salts of iron(VI) ion. (C) 2007 Elsevier B.V. All rights reserved.

The first spectroscopic evidence for complexes containing iron formally in the IV and V oxidation states in the presence of a simple ligand, i.e., OH/sup -/ and P/sub 2/O/sub 7//sup 4 -/ in alkaline solution is reported. These transient species are obtained by pulseradiolysis of alkaline ferric (Fe(III)) and ferrate (Fe(VI)) solutions by using the hydroxyl radical or its conjugate base, O/sup -/,
