    • A method of producing ferrate is disclosed, in which Fe.sup.3+ is oxidized with monoperoxosulfate (HSO.sub.5.sup.-) to form K.sub.2 FeO.sub.4 /K.sub.2 SO.sub.4. The isolation of the potassium ferrate (K.sub.2 FeO.sub.4) product in a sulfate matrix (K.sub.2 SO.sub.4) stabilizes the ferrate against decomposition and inhibits clumping of the solid product by inhibiting moisture adsorption. The method is a safe, simple process for the production of ferrate that is reliable, fast, and inexpensive, and that avoids the use of chlorine or chlorinated products, thus avoiding their harmful side effects. The improved ferrate product of this method is particularly useful for water and wastewater treatment, especially in the treatment of sulfides and hydrazines, and in other applications.
    • 公开了一种生产高铁酸盐的方法,其中Fe3 +被单过氧硫酸盐(HSO5-)氧化以形成K 2 FeO 4 / K 2 SO 4。 在硫酸盐基质(K2SO4)中高铁酸钾(K2FeO4)产物的分离使高铁酸盐不会分解,并通过抑制水分吸附来抑制固体产物的结块。 该方法是可靠,快速且廉价生产高铁酸盐的安全,简单的方法,避免使用氯或氯化产物,从而避免其有害的副作用。 该方法的改进的高铁酸盐产物特别适用于水和废水处理,特别是在硫化物和肼的处理中以及在其它应用中。
