“…This positive influence of temperature was already observed by Pick [11] and other authors [117,118]. Bouzek et al [49][50][51][52][53] studied different iron anode materials and concluded that pure iron had the strongest tendency to form a compact and stable surface layer. A higher temperature, 30-50 • C depending on the electrolysis conditions, is necessary to overcome this problem.…”

“…There has been a marked increase in new applications of ferrate(VI) , in particular the utilization of ferrate in organic synthesis [22][23][24][25][26], corrosion protection [27] and environmental improvement [28][29][30][31][32]. More recent research on ferrate(VI) also has involved the development of new characterization techniques that allow deeper insight into the reaction mechanisms and properties of ferrate(VI) [45][46][47][48][49][50][51][52][53][54].…”

Context: Coagulation, chemical oxidation and disinfection are essential processes in water and waste treatment. A chemical that can be applied for all the above mentioned purposes is ferrate(VI). Although there are many studies about ferrate(VI), no comprehensive review paper can be found about ferrate(VI) from production to applications. The aim of this study was to review ferrate(VI) production, measurement, stability and utilization in water and wastewater treatment.Evidence Acquisition: In acidic conditions, the oxidation and reduction capacity of ferrate(VI) is superior to all currently utilized oxidizers and disinfectants in water and wastewater treatment. New researches have provided the technology of using ferrate(VI) for coagulation, chemical oxidation and disinfection of water and wastewater in a reactor simultaneously, which can reduce the size of water and wastewater treatment plants and increase the treatment efficiency.Results: Despite the existence of these technologies, there is no full-scale application of ferrate(VI) in the water and wastewater industry which it is due to difficulties associated with I, the lack of adequate researches that have demonstrated its capabilities and advantages over the existing water and wastewater treatment methods; ii, the instability of ferrate(VI) depending on its method of preparation, and iii, the relatively low yield of ferrate(VI). Conclusions:To solve the above mentioned difficulties, fundamental study most be carried out to discover the novel methods of ferrate(VI) production, focusing on increasing the product stability and the production yield.

“…The electrolytes in both compartments were 0.3 mol/L NaOH solution, and their volume was 100 mL. The anode was activated by cathodic polarization for 30 min at a constant current of 1.0 A before the start of electro-synthesis [26]. Cell temperature was controlled within 711C by ice-water cooling bath.…”

Based on the quenched chemiluminescence intensity of the luminol reaction sensitized by ferrate(VI) in alkaline medium, a novel CE with on-line inhibited method for the simultaneous analysis of benzenediol isomers was developed. The ferrate(VI) solution was freshly prepared by electrochemical technique before electrophoresis. The parameters influencing detection and separation were carefully investigated. Baseline separation of benzenediols including catechol, resorcinol, and hydroquinone was achieved in less than 8 min with 5.0 mmol/L sodium tetraborate and 2.0 mmol/L luminol at an applied voltage of 18 kV. The LODs (S/N=3) for catechol, resorcinol and hydroquinone were determined to be 8.5 x 10(-9), 8.0 x 10(-7) and 6.5 x 10(-9) mol/L, respectively. Finally, the proposed method was applied for phenolic compounds in hair dye.
