摘　　要：以铁丝网作阳极,应用电解氧化法制备FeO42-溶液,并合成固体K2FeO4.研究电解条件(如搅拌、超声、静置、温度、电流密度等)对该制备过程电流效率的影响规律.结果表明:以14 mol/L NaOH作电解液,于30℃、10 mA.cm-2及搅拌作用下电解,可获得较高的电流效率.The FeO4^2- was synthesized using iron lattice as anode and the solid K2 FeO4 was also prepared. Influence of electrolytic conditions, such as stir, ultrasonic, temperature and current density on the current efficiency were studied. The results showed that preferable ferrate（VI） current yield was obtained in a current density of 10 mA · cm^2, temperature 30℃ and 14 mol/L NaOH as electrolyte under at stirring effect.
