| titleOfInvention | Preparation method of potassium ferrate |
| abstract | The invention discloses a preparation method of potassium ferrate, which comprises the following steps: adding potassium hydroxide into water while stirring, thus forming a potassium hydroxide saturated solution in the water; slowly adding ferric nitrate, stirring to dissolve the ferric nitrate, adding potassium hypochlorite, then adding a stabilizer, and reacting at normal pressure for 60-90 minutes until the solution is transparent; cooling, and then filtering to obtain a crude product; and dissolving the crude product in 3-4 mol/l potassium hydroxide solution, stirring at low temperature for a certain time, filtering, washing with solvent, heating, vacuumizing, and drying to obtain the target product potassium ferrate. The invention uses the high-efficiency stabilizer, and has the advantages of reaction time shortening, reaction temperature reduction, high product yield and stable performance. |
