“…It was interesting to note that the admissible limit of arsenic in drinking water as suggested by WHO (10 ppb) was crossed only when pH of the solution was increased above 6.08, while 100% removal was observed at pH 3.54 (Table , column 5). At lower pH, the oxidative nature of ferrate is increased . Moreover, protonation of the surface of adsorbent at low pH also facilitates the adsorption of negatively charged arsenate (AsO 4 3– ) ions through electrostatic attraction.…”

The present study shows arsenic removal and bactericidal efficiency of sodium ferrate with various adsorbents to decontaminate water. Among the tested adsorbents, the ash of Unio (Lamellidens marginalis) shells was found to be the best. It reduces 500 ppm arsenic in water to <10 ppb in 40 min by adsorption. As(III) was converted into As(V) by in situ prepared Na 2 FeO 4 , which was then removed by adsorption on to the ash of Unio. Bactericidal potential of sodium ferrate for the bacterium E. coli was found better than those of three antibiotics viz. moropenum, vancomycin, and piperacillin tozabactum, and it was found at par with ampicilin. Bactericidal effect was found due to the leakage of protein from the cell wall. Effects of different process variables on the extent of removal of As(V) were studied. Composition of ash and morphological changes after adsorption were determined with Fourier transform infrared (FT-IR), X-ray diffraction (XRD), and scanning electron microscopy (SEM) studies.

“…4, only 37.9% desulfurization rate was obtained without SZ. This is understandable, because of the poor solubility of K 2 FeO 4 in common organic phases and the low reaction rate [6]. The desulfurization rate increased rapidly with the SZ amount at the beginning, reaching 59.2% for 0.20 g of SZ.…”

“…Especially, SO 4 2− /M x O y catalyst exhibits excellent catalytic activity and selectivity for all acid-catalyzed reactions and therefore has attracted much attention [5]. Previous studies by our group revealed that the reactivity of K 2 FeO 4 for oxidation of benzyl alcohol in organic solvent can be greatly enhanced by addition of a small amount of acid solution at room temperature [6,7]. Therefore, we speculated that a solid superacid would be a promising catalyst for K 2 FeO 4 -mediated ODS.…”

A catalyst comprising SO42–/ZrO2superacid was prepared by impregnation and characterized by FT-IR, XRD, and BET. A novel procedure for oxidative desulfurization of simulated light fuel oil using K2FeO4over the SO42–/ZrO2solid superacid was developed. The effects of the oxidantion and extraction conditions on desulfurization were investigated. At temperature of 30 °C, SZ of 0.2 g, K2FeO4of 0.2 g, reaction time of 1 h, 20 mL of oil is oxidized, followed by methanol extraction at 15 °C for 10 min with the volume ratio of solvent/oil of 1, the results display desulfurization rate for simulated light fuel oil and straight-run gasoline were 88.2% and 89.2%, respectively.

“…In particular, high redox potentials up to 2.2 V can be theoretically obtained at low pH, but its rapid decomposition makes the fascinating oxidizing power inaccessible in real applications. Second, ferrate(VI) solid is insoluble in organic solvents,, thus most of its oxidizing capability is actually “hidden” inside the solid structure and the accessible surface will be gradually passivated by the resultant Fe III during reaction, which are undesirable for efficient/effective oxidative transformations. Third, the hazardous organic solvents (e.g., benzene, cyclohexane, pentane) and corrosive conc.…”

The +6 oxidation state of iron generally exists in the form of ferrate(VI) with high redox potential and environmentally friendly nature. Although ferrate(VI) has been known for over a century, its chemistry is still limited to the solvent‐based reactions that suffers from the insolubility/instability of this oxidant and the environmental issues caused by hazardous solvents. Herein, we explore the solvent‐free reactivity of ferrate(VI) under mechanical milling, revealing that its strong oxidizing power is accessible in the “dry” solid state towards a broad variety of substrates, for example, aromatic alcohols/aldehydes and carbon nanotubes. More significantly, solvent‐free mechanochemistry also reshapes the oxidizing ability of ferrate(VI) due to the underlying solvent‐free effect and the promotive mechanical actions. This study opens up a new chemistry of ferrate(VI) with promising application in green oxidative transformation of both organic and inorganic substrates.
