In the traditional oxidation process an Fe(Ⅲ) compound is put into a high-alkali solution of sodium hypochorite to produce a ferrate (Ⅵ) solution.In this work ferric chloride was converted into potassium fluoferrite,which was used to produce a ferrate (Ⅵ) solution.The results show that the yield was obviously improved,and the product stability was increased.The process conditions were optimized.Ferric chloride and potassium fluoride were mixed in a mole ratio of 1:9 to produce potassium fluoferrite,which was put into a high-alkali solution of sodium hypochlorite at a constant temperature of 45℃ for 90 min,and the product concentration of the Ferrate (Ⅵ) solution reached about 0.2 mol/L.
