Nitrogen-containing pollutants have been found in surface waters and industrial wastewaters due to their presence in pesticides, dyes, proteins, and humic substances. Treatment of these compounds by conventional oxidants produces disinfection by-products (DBP). Ferrate(VI) (Fe(VI)O(4)(2-), Fe(VI)) is a strong oxidizing agent and produces a non-toxic by-product Fe(III), which acts as a coagulant. Ferrate(VI) is also an efficient disinfectant and can inactivate chlorine resistant microorganisms. A novel ferrate(VI) technology can thus treat a wide range of pollutants and microorganisms in water and wastewater. The aim of this paper is to review the kinetics and products of the oxidation of nitrogen-containing inorganic (ammonia, hydroxylamine, hydrazine, and azide) and organic (amines, amino acids, anilines, sulfonamides, macrolides, and dyes) compounds by ferrate(VI) in order to demonstrate the feasibility of ferrate(VI) treatment of polluted waters of various origins. Several of the compounds can degraded in seconds to minutes by ferrate(VI) with the formation of non-hazardous products. The mechanism of oxidation involves either one-electron or two-electrons processes to yield oxidation products. Future research directions critical for the implementation of the ferrate(VI)-based technology for wastewater and industrial effluents treatment are recommended.

“…CuBr/air showed lower activity (entries 4 and 5) and CuI/air appeared to be inert in this reaction (entries 6 and 7). In this reaction, several commonly used solvents were tested ( [13][14][15][16][17]. Acetonitrile, toluene, pyridine, and triethylamine were much more effective to give high yields for this reaction (entry 1 and entries 10-12).…”

“…6 A variety of oxidation methods have been reported for the preparation of these compounds. For example, aromatic amines can be oxidized with oxidants such as peracetic acid, 7 manganese dioxide, 8 lead tetraacetate, 9 Hg(OAc) 2 , 10 barium manganate, 11 phenyl iodoacetate, 12 sodium hypochlorite, 13 potassium ferricyanide, 14 potassium ferrate, 15 barium ferrate monohydrate, 16 and mercury(II) oxide. 17 Most of these methods are based on stoichiometric processes.…”

“…Fe(VI) has been known to react with electron-rich organic moieties (ERM) through electrophilic oxidation mechanism (Lee et al, 2009). The proposed mechanism for the oxidation of aniline (Huang et al, 2001b) or phenol (Huang et al, 2001a) by Fe(VI) involves a free radical reaction mechanism through an associative type of mechanism with hydrogen bond formation in the activated complex accompanied by intermolecular electron transfer. Nevertheless, there has so far been no study on the oxidation of BTs by Fe(VI) available in the literature, especially on their reaction mechanisms.…”
