The influence of electrolyte composition on electrochemical ferrate(VI) synthesis. Part I: anodic dissolution kinetics of pure iron

Popis výsledku v původním jazyce

The influence of anolyte composition and temperature on the anode dissolution kinetics of pure iron and subsequent ferrate(VI) production was studied by means of potentiodynamic voltammetry and electrochemical impedance spectroscopy. The results obtainedwere verified by batch electrolyses. Pure NaOH, KOH, and mixtures thereof were used as an anolyte. The motivation for this study is to understand in more detail the electrolysis process at which ferrate(VI) is electrochemically produced in situ in the solid form which is more suitable for practical utilization. A significant impact of the anolyte composition on the system behavior was indicated. It is related to the solubility of the anode dissolution products in the anolyte. It was concluded that thefast reaction kinetics in the transpassive potential region is connected with a deterioration of the ferrate(VI) synthesis efficiency. This is explained by the kinetic enhancement corresponding to the intensification of oxygen evolution a
