This study deals with the influence of the anode material and the electrolyte composition on the kinetics of the electrode dissolution and on the Ferrate(VI) formation. The cast iron rich in iron carbide and the silicon rich steel are compared as perspective materials that provide the highest current efficiency of the electrochemical synthesis process. Pure NaOH, KOH solutions and their mixtures were used as an electrolyte. Electrochemical impedance spectroscopy was used to quantify the influence of the individual parameters on the anode dissolution kinetics. The results were compared with the pure iron study results, in order to assess impact of the individual anode material components on the anode's behavior. The theory, derived on the basis of the electrochemical impedance spectroscopy and cyclic voltammetry data, was confirmed by the batch electrolysis experiments. 2008 American Chemical Society.
