Abstract: The ferrate(Ⅵ) was synthesized by electrochemical anodic oxidation. The effects of preparation conditions on the current yield of ferrate(VI) synthesis have been studied in this work. The experimental results showed that grey cast iron as an anodic material is suitable for electrochemical synthesis and NaOH solution as an electrolyte results in a higher current yield than KOH solution. The highest current yield was obtained at a current density (4.54) mA· cm~(-2),temperature 20　℃ and 14 mol·dm~(-3) NaOH. In this case, a current yield of 68.5% was obtained by electrolysis for 1 h.

Key words: Ferrate(VI), Current yield, Polarization curve
