Fund Project:

By electrolyzing iron net anode in 14 mol/L NaOH solution in a diaphragm electrolyzer with anodic chamber gap of 15 to 22 mm, Na₂FeO₄ in concentration of 0.23 to 0.32 mol/L could be obtained when the apparent anodic current density was of 160 to 280 A/m² and the electrolysis time for 5~6 hours. Adding the Na₂FeO₄ and KOH solutions alternately to the reactor at 20℃ and the reaction time of 30 min, the solid K₂FeO₄ with purity over 95% could be obtained after precipitation, washing and drying. It is found that the dissolution of K₂FeO₄ in solutions of KOH, NaOH and in their mixture was affected by common ion effect as well as strong salting-out effect. The reduction rate of soild K₂FeO₄ by methanol was proportional to the content of water in methanol solution.
