Abstract
The influence of anode composition and temperature on the anode electrochemical activity and subsequent ferrate(VI) production in 10 M NaOH solution has been studied. Results obtained from the pure iron, gray and white cast iron were compared to establish the most promising anode in terms of ferrate production efficiency. The cyclic voltammetry measurements associated with the potentiodynamic polarization results induce that the pure iron has the lowest electrochemical activity. Presence of silicon in outer layer was confirmed by X-ray diffraction of reaction products on WCI and GCI in the form of iron(II)iron(III) silicon oxide–hydroxide.
