“…Absorbable organic haloids (AOX) in ferrate(VI) treated wastewater effluents were observed although the AOX concentration rise was lower than that in the chlorination process. 89 Obviously, more studies need to be carried out to investigate the formation potential of harmful byproducts during ferrate(VI) treatment. For example, it has yet to be established under which operating conditions and for which original pollutants, harmful by-products are formed.…”

Ferrate(VI) ion has the formula FeO 4 2− , and possesses unique properties, vs. strong oxidising potential and simultaneous generation of ferric coagulating species. For this reason, a number of studies have been carried out to investigate the preparation, characterisation and application of ferrate(VI) for water and wastewater treatment. These studies revealed that ferrate(VI) can disinfect microorganisms, partially degrade and/or oxidise organic and inorganic impurities, and remove suspended/colloidal particulate materials in a single dosing and mixing unit process. Most recently, research groups globally have reported using ferrate(VI) to treat emerging micropollutants in water purification processes. Work has not only been limited to fundamental studies but has been driven by the ideas of putting the application of ferrate(VI) into practice; the advantages of the application of ferrate(VI) over existing water and wastewater treatment methods should be shown as should other benefits to the water industry of its use. This paper thus reviews advances in the preparation and use of ferrate(VI), discusses the potential full scale application of ferrate(VI) in water purification and recommends required future research in order to implement ferrate(VI) in practice.

“…In addition, various studies indicate that Fe(VI) is a selective oxidizing agent that reacts with target compounds, such as phenol, chlorophenol, 3-methylphenol benzene series, methyl tert -butyl ether, acetaminophen, trichloroethylene, methanol, sulfite, and cyanide. 24−29 In addition, the final product of Fe(VI) decomposition is ferric iron (Fe(III) solid), which may play an important role in the subsequent water treatment process, such as adsorption and coagulation.…”

This study investigates the degradation of dimethyl phthalate (DMP) with hydrogen peroxide and ferrate (Fe(VI)) under various reaction conditions. The results showed that the optimum conditions for dimethyl phthalate removal from water were as follows: (a) pH 7.0 and (b) the original molar ratio of [Fe(VI)]/[H 2 O 2 ]/[DMP] equal to 10:2:1. Under the optimum conditions, the degradation rate of DMP can reach 89.7% in 360 min. Furthermore, 2,5-dihydroxybenzaldehyde, isophthalic acid, 2-ethylhexanol, oxalic acid, 2,6-dihydroxybenzoic acid, 2,6-dihydroxybenzaldehyde, 2,5-dihydroxybenzoic acid, and monomethyl phthalate were identified as the degradation intermediates, and degradation pathways were proposed.

“…Bacterial growth was detected in a liquid growth medium (tryptone 6 g/L, yeast extract 3 g/L; pH 7.2 ± 0.2) after 72 hr incubation at 22 ± 1°C. The MPN values were calculated as described in previous publications (Garthright and Blodgett, 2003;Gombos et al, 2013). The removal efficiency (%) of each component was calculated as concentration differences between raw and treated samples.…”
