摘要 以金属铁为正极、以铂为负极材料,13 5mol·dm-3氢氧化钾溶液为电解液在隔膜电解池中电化学合成高铁酸钾。理想合成温度为30℃,电流密度约为0 5mA cm2,在饱和氢氧化钾溶液中合成电流效率为58 7%。充电电压为1 92~1 83V。电化学合成时间为2~3h。 The electrochemical synthesis of potassium ferrate was carried out in membrane cell with metal iron as anode and platinum as cathode in electrolysis of 13.5 mol·dm^(-3) KOH solution.The optimum temperature of synthesis is about 30℃.Current density is about 0.5 mA/cm^2.The current efficiency of the synthesis in 13.5 mol·dm^(-3) KOH solution is 58.7%.Charging voltage was varied between 1.92 to (l.83 V).Electrochemical synthesis time is about 2 to 3 hours.
