“…Salts of higher oxidation states of iron ranging from þ4 to þ8 have also been synthesized in laboratory (Atanasov, 1999;Bielski, 1990;Bielski and Thomas, 1987;Dedushenko et al, 2008;Hoppe and Mader, 1990;Jeannot et al, 2002;Kokarovtseva et al, 1972;Kopelev et al, 1990Kopelev et al, , 1992Kopelev, 1997;Perfiliev and Sharma, 2008;Perfiliev et al, 2006;Perfliev, 2002). Ferrate(VI) Fe VI O 2À 4 has been of great interest because of its role as an oxidant and hydroxylating agent in industrial and water treatment processes, such as the development of a "super iron" battery, green chemistry synthesis, and non-chlorine oxidation for pollutant remediation (Bartzatt and Carr, 1986;Carr et al, 1985;Johnson et al, 2008;Hornstein, 1994, 1996;Licht et al, 1999;Licht and Yu, 2008;Sharma, 2002a;Sharma et al, 2005a,b) Ferrate(VI) provides an environmentally benign high energy density cathode for batteries (Licht et al, 2009(Licht et al, , 1999Licht, 2010;Licht and TelVered, 2004).…”

Fe(IV) and Fe(V) are promising oxidants for the selective removal of emerging organic contaminants (EOCs) from water under near-neutral conditions. The Fe(III)-assisted electrochemical oxidation system with a BDD anode (Fe(III)–EOS–BDD system) has been employed to generate Fe(VI), while the generation and contributions of Fe(IV) and Fe(V) have been largely ignored. Thus, we examined the feasibility and involved mechanisms of the selective degradation of EOCs in the Fe(III)–EOS–BDD system under near-neutral conditions. It was found that Fe(III) application selectively accelerated the electro-oxidation of phenolic and sulfonamide organics and made the oxidation system be resistant to interference from Cl–, HCO3 –, and humic acid. Several lines of evidence indicated that EOCs were decomposed via direct electron-transfer process on the BDD anode and by Fe(IV) and Fe(V) but not Fe(VI), besides HO•. Fe(VI) was not generated until the exhaustion of EOCs. Furthermore, the overall contributions of Fe(IV) and Fe(V) to the oxidation of phenolic and sulfonamide organics were over 45%. Our results also revealed that Fe(III) was oxidized primarily by HO• to Fe(IV) and Fe(V) in the Fe(III)–EOS–BDD system. This study advances the understanding of the roles of Fe(IV) and Fe(V) in the Fe(III)–EOS–BDD system and provides an alternative for utilizing Fe(IV) and Fe(V) under near-neutral conditions.
