Preparation of Ferric sulfate. Firstly, ferrous sulfate is dissolved in water, heated to 70 °C. Slowly adding sulfuric acid and nitric acid to solution for oxidation reaction at the temperature of 95-100 °C. When the oxidation reaction is complete, reactant is filtered and adding a small amount of sulfuric acid to the filtrate. Then product is obtained by evaporation, condensation, cooling and filtering out the crystals.
