Abstract：Ferrate(Ⅵ)is generated the electrochenical oxidation of porous magnetite electrodes，by melt-ing pure magnetite grain.Pretreatment of the anode by cathodic polarization is necessary for ferrate(Ⅵ)genera-tion and the achievement of high current efficiency at magnetiet electrode.An optimum synthesis electrolyte is ob-served to be 16 mol·L-1NaOH.In this electrolyte the effects of anode current density，J，om Fe(Ⅵ)synthesis rate，current efficiency and internal cell temperature are studied.An optimum result is obtained at J=3.3mA·cm-2，30℃ in 16 mol·L-1NaOH for 5 h.
