“…The degradation of in these pollutants must be supported by UV light to achieve photocatalytic decomposition on TiO 2 and other oxide particles . It is important to note that perfluoroalkylsulfonates and ‐carboxylates are resistant to ferrate(VI) oxidation but can be attacked by ferrate(V) and ferrate(IV) which may be addressed as “activated” ferrates(VI) …”

The history of the oxo compounds of iron in its highest oxidation states is reviewed and modern activities in this long neglected area of inorganic chemistry are highlighted. The chemistry of ferrates(VI) is the most rapidly advancing branch owing to several potential applications in diverse fields such as environmental chemistry and energy storage. Convenient and high‐yield preparations of ferrates(VI) in high purity are presented, followed by a coverage of the analytical, spectroscopic, and structural characterization in the solid and in solution, with a focus on the stability of these compounds, which had long been under‐estimated. Particular attention has been paid to the fascinating mechanisms that have been proposed for the intriguing “self‐decay” of the [FeO4]2– dianion. Redox processes with inorganic and organic substrates are summarized including fresh and waste water treatment on the one hand and “super‐iron batteries” on the other. Recent advances in the experimental and computational approach to ferrates(VII) [FeO4]– and the elusive “iron tetroxide” [FeO4] are described.

“…An alternate preoxidant, chloramine, may form nitrosoamianes [12,13]. Ferrate(VI) (Fe VI O 4 2− , Fe(VI)), an environmentally-friendly iron-containing material, is a potential emerging oxidant [14][15][16][17]. Fe(VI) as an pre-oxidant can be effective in decreasing the level of DBPs produced during subsequent chlorination.…”

“…The spontaneous decomposition of Fe(V) is another an important aspect with the release of Fe(III) ion and hydrogen peroxide in alkaline medium illustrated in Eq. (8) [38,39]. Ferric hydroxide can cause coagulation and hydrogen peroxide also has a strong oxidabillity, leading to a higher degradation of AMI and NOR with UV irradiation.…”

The oxidation of amitriptyline (AMI) and nortriptyline (NOR), two typical tricyclic antidepressants, has been studied in ferrate(VI) (Fe(VI)) solution. The removal rate of AMI and NOR increased with increasing Fe(VI) dosage and was seen to be pH dependent in the order pH 7.0 < 10.0 < 8.0 < 9.0. UV irradiation at 254 nm was found to exert a synergistic effect on the Fe(VI) oxidation of AMI and NOR. By LC-ESI-MS/MS analysis, the main oxidation products of AMI and NOR by Fe(VI) have been identified. The exocyclic double bond is first oxidized to give the exo-epoxide, which is then hydrolyzed and finally oxidized to give dibenzosuberenone and 3-dimethylamino-propionaldehyde. The results suggest that Fe(VI) has a good ability to oxidize AMI and NOR in aqueous solution and could be an effective treatment method for the purification of waters containing these particular antidepressants.
