Abstract： |
The invention relates to a preparing method for ferrocyanide with high load/silica hybrid material, belonging to a preparing method for radionuclide ion absorbing material. The method uses the salt solution with metal ion such as Mn, Sn, Ti, Fe, and Ni so on to react with potassium (sodium) ferrocyanide so as to obtain nanometer particle of ferrocyannide. The particle is fixed by silica solution in water system or is fixed by polymerization siloxane in organic solvent and proper inorganic acid, organic amine or amine water is added to obtain hybrid gel. The hybrid gel is dried, rubbed and screened to obtain ferrocyanide with high load/silica hybrid material. The high load of the material is high and the absorption to nuclide ion is strong. In addition, the material intensity can satisfy the demand of packed bed. The particle diameter can be controlled so as to avoid the problem that the water resistance of bed layer generated by ferrocyanide used alone is overlarge. |
