Electrochemical Preparation of Sodium Ferrate(VI) Using Silicon Iron as Anode in Non-Diaphragm Electrobath

Using silicon iron as anode to preparation sodium ferrate(Ⅵ) in non-diaphragm electrobath.The maximum current yield was reached to 43.0%(concentration of ferrate(Ⅵ) is( 0.079mol·L~(-1) )) under condition that take 40% sodium hydrate as electrolyte in which containing 1% sodium silicate,reaction temperature is around 35℃,current density equals 40mA·cm~(-2) and electrolysis duration is 180mins.It proved that silicon iron anode is better than other reported anode,such as carbon iron or zinc white iron anode ect..
