There is described a method for extracting fluoride ions from a nuclear fuel solution which comprises treating said solution with a solid phase from hydrated silica, such as silica gel and/or silicic acid, to bind the fluorine to the silicium, said solid phase then being separated from said solution.

Method for extracting fluoride ions from a nuclear fuel solution

The method comprises the steps of preparing a solution of a binder in a solvent, wetting and grinding polyantimonic powder, forming a suspension with the wetted and ground powder and the solvent, mixing the suspension with the solution, pouring on a plate the so obtained viscous liquid, allowing the solvent to evaporate until a membrane in formation begins to dry, removing further the solvent by lixiviation, and removing the membrane from the plate.
