The influence of electrolyte composition on electrochemical ferrate(VI) synthesis. Part II: anodic dissolution kinetics of a steel anode rich in silicon
Original language description
The anolyte composition and process temperature could improve the kinetics of iron anode dissolution and subsequent ferrate(VI) production significantly. This also holds for the anode composition. Silicon-rich steel (SRS) was employed as the anode material to produce ferrate(VI), and the characteristics observed were compared with those of the pure iron anode obtained during our previous study. Using anolytes 14 M NaOH, 14 M KOH and mixtures thereof, the systems were studied by means of potentiodynamicmethods, electrochemical impedance spectroscopy and batch electrolysis experiments. In addition, scanning electron microscopy and metallographic images of the material surface were taken to identify changes in the phase composition of the material, caused by anodic polarization in strongly alkaline solutions. The dissolution kinetics increases with increasing temperature and, at 60 °C, also with increasing K+ content in the anolyte. Compared to iron, SRS easily dissolves into ferrate(VI)
