报导氢氧化铁对ＦｅＯ２－４水解反应的催化作用及温度、浓度、碱度等对ＦｅＯ４２－稳定性的影响．ＦｅＯ２－４的稳定性随体系中Ｆｅ（ＯＨ）３的增多和ＦｅＯ４２－浓度增大而变小；当ＯＨ－浓度低于１．０ｍｏｌ／Ｌ时，ＦｅＯ２－４的稳定性不受碱度影响；在室温下，ＦｅＯ２－４的稀溶液是稳定的。用这些重要规律指导高铁酸钾的合成，取得满意的结果
Abstract：The catalytic behaviour of Fe(OH) 3 for the hydrolysis reaction of ferrate(VI) is reported.The effect of temperature, concentration and alkalinity on stability of aqueous ferrate(VI) solutions was studied. It has been descovered that the stability of FeO 2- 4 decreased with increasing amount of Fe(Ⅲ) and with increasing concentration of FeO 2- 4, that the solubility of FeO 2- 4 was not affected by alkalinity at the concentration of OH - below 1.0 mol/L, and that dilute solution of FeO 2- 4 is stable at the normal temperature . These important laws have been used to the synthesis of potassium ferrate(VI) with satisfactory results.
