高铁酸钾电化学合成研究

Study on Electrochemical Synthesis of Potassium Ferrate

以细铁丝为阳极,铂片为阴极,KOH溶液为电解液电解合成高铁酸钾,在KOH溶液浓度12mol dm-3,电流密度2mA·cm^(-2),温度25℃电解1．5h条件下,获得最佳合成效率54．2％．

Potassium ferrate was synthesized in solution of KOH with iron silk as anode and platinum as kathode, there was the best efficient of 54.2% under the condition：the eonentration of solution of KOH was 12mol·dm^-3, current density was 2 mA·cm^-2,the lemperalure was 25℃,and duration was 1.5h.
