Embodiment 1
[0046] Take by weighing 0.2mol of zinc chloride, be dissolved in 200ml of deionized water, stir evenly to obtain a zinc chloride solution with a substance concentration of 1mol / L; weigh 0.2mol of Prussian blue sodium ferrocyanide, dissolve In 200ml of deionized water, stir evenly to obtain a sodium ferrocyanide solution with a substance concentration of 1mol / L; add 0.1mol of solid sodium chloride to the sodium ferrocyanide solution, stir evenly, and make Sodium chloride is completely dissolved in the sodium ferrocyanide solution to obtain a mixed solution of sodium ferrocyanide and sodium chloride; the zinc chloride solution is added dropwise to the mixed solution, and magnetic stirring is performed while adding. After completion, continue to stir for 2 hours to obtain a white suspension; let the white suspension stand still for 1 hour, precipitate, and centrifuge to obtain a white solid; wash the white solid with deionized water several times to obtain the ferrous Sodium zinc...
Embodiment 2
[0048] Take by weighing 0.6mol of zinc chloride, be dissolved in 200ml of deionized water, stir evenly to obtain a zinc chloride solution with a substance concentration of 3mol / L; weigh 0.6mol of Prussian blue sodium ferrocyanide, dissolve In 200ml of deionized water, stir evenly to obtain a sodium ferrocyanide solution with a substance concentration of 3mol / L; add 0.6mol of solid sodium chloride to the sodium ferrocyanide solution, stir evenly, and make Sodium chloride is completely dissolved in the sodium ferrocyanide solution to obtain a mixed solution of sodium ferrocyanide and sodium chloride; the zinc chloride solution is added dropwise to the mixed solution, and magnetic stirring is performed while adding. Continue to stir for 4 hours after completion to obtain a white suspension; let the white suspension stand still for 3 hours, precipitate, and centrifuge to obtain a white solid; wash the white solid with deionized water several times to obtain the ferrous Sodium zinc...
Embodiment 3
[0050] Weigh 0.1mol of zinc sulfate, dissolve it in 200ml of deionized water, and stir evenly to obtain a zinc sulfate solution with a concentration of 0.5mol / L; weigh 0.2mol of Prussian blue sodium ferrocyanide, dissolve in In 200ml of deionized water, stir evenly to obtain a sodium ferrocyanide solution with a substance concentration of 1mol / L; add 0.8mol of solid sodium chloride to the sodium ferrocyanide solution, stir evenly, and make the chlorine Sodium chloride is completely dissolved in the sodium ferrocyanide solution to obtain a mixed solution of sodium ferrocyanide and sodium chloride; the zinc sulfate solution is added dropwise to the mixed solution, and magnetic stirring is performed while the addition is completed. Stirring was continued for 6 hours to obtain a white suspension; the white suspension was left to stand for 4 hours, precipitated, and centrifuged to obtain a white solid; the white solid was washed with deionized water several times to obtain the ferro...
