“…Ferrate(VI) has high redox potential under acidic conditions, and thus it has been successfully applied in water remediation and treatment processes [25][26][27]. Currently there is not enough information available on the performance optimization of pharmaceutical treatment by electrosynthesized ferrate(VI) ion.…”

Hexavalent iron species (Fe(VI)) have been known for over a century, and have long-time been investigated as the oxidant for water purification, as the catalysts in organic synthesis and more recently as cathodic charge storage materials. Conventional Fe(VI) syntheses include solution phase oxidation (by hyphchlorite) of Fe(III), and the synthesis of less soluble super-irons by dissolution of FeO 4 2-, and precipitation with alternate cations. This paper reviews a new electrochemical Fe(VI) synthesis route including both in situ and ex situ syntheses of Fe(VI) salts. The optimized electrolysis conditions for electrochemical Fe(VI) synthesis are summarized. Direct electrochemical synthesis of Fe(VI) compounds has several advantages of shorter synthesis time, simplicity, reduced costs (no chemical oxidant is required) and providing a possible pathway towards more electro-active and thermal stable Fe(VI) compounds. Fe(VI) analytical methodologies summarized in this paper are a range of electrochemical techniques. Fe(VI) compounds have been explored as energy storage cathode materials in both aqueous and non-aqueous phase in ''super-iron'' battery configurations. In this paper, electrochemical synthesis of reversible Fe(VI/III) thin film towards a rechargeable super-iron cathode is also summarized.

“…Similarly, the secondary effluent disinfection study showed 99.9% of total coliforms and 97% of the total viable bacteria were removed at a dose of 8 mg/L of ferrate(VI) (cf Figure 18) [89]. The real sewage wastewater and a model water E. coli (concentration 3.2x10 8 /100mL) were used to assess the Fe(VI) capability as coagulant behavior (compared to ferric and aluminum sulfate) for real wastewater and disinfection for the model E.coli water (compared with sodium hypochlorite) [90]. The Fe(VI) showed significantly better performance over ferric and aluminum sulphate.…”

“…can be written as k = k'C b to relate the rate constant of inactivation to the disinfectant concentration C. b is termed as dilution coefficient and can be obtained by the slope of a loglog plot of t vs C. Previously, the k was evaluated for E. coli using the equation (51) at different pH for the disinfection of E. coli [90]. The modified Delayed Chick-Watson law with time averaged Fe(VI) concentration (equation (52)) was used in order to discuss the kinetics of the inactivation [27,92].…”
