A method for the removal of fluorine compounds from admixture with phosphoric acid in which the mixture in organic solvent is contacted with an aqueous solution of a compound of Al, Fe, Ti or Zr whereby the phosphoric acid remains in the organic solvent phase while the fluorine compounds are extracted in the aqueous phase, and then regenerating the organic solvent phase with water to remove phosphoric acid from the solvent phase. |
