Název v původním jazyce

Electrochemical formation of ferrate(VI) in a molten NaOH-KOH system.

Popis výsledku v původním jazyce

Ferrate(VI) (FeO42-) has been produced electrochemically for the first time in a molten NaOH-KOH mixture at 200 oC. The virtual complete absence of water in the system avoid decomposition of ferrate(VI) due to reduction by water. Cyclic voltammetry was used to characterize the synthesis process. Formation of FeO42- was observed at an inert electrode in a molten mixture having Fe(III) ions. Use of iron electrode in a molten mixture also resulted in FeO42- ion. An anodic wave corresponding to the FeO42- ion production was observed in the potential region where evolution of oxygen commences. The counter current peak during the cathodic potential scan indicates no or insignificant passivation of the iron electrode surface at FeO42- formation potentials. Molten salt electrochemical ferrate(VI) synthesis method offers thus, beside avoiding product decomposition by the reaction with water, several additional advantages over synthesis in water environment. As the most significant lack of passi
