Title: Process for chemically separating substances in solution
Inventor: LAVEISSIERE FRANCOISE
IPC: G21F9/12
Filed: 1964-03-11
Abstract: A substance, e.g. Cs or Sr, existing in the form of a salt dissolved in a solvent, in mixture with other substances from which it is desired to separate it, is extracted by selective fixation upon a solid insoluble in this solvent, the process comprising the stages of preparation of a fine dispersion of the fixative solid in colloidal form, of flocculation of the colloid, of extraction of the flocculate and its dispersion in an organic solvent, and of placing the dispersion in contact with the solution of the substance to be extracted. By way of example, Cs present as a fission product in its nitrate form is separated from an aqueous solution, possibly containing salts of other fission products, by preparing a colloidal dispersion of mixed ferrocyanides which contains cations from transition elements and monovalent cations, adding a surface-active agent comprising a quaternary ammonium salt to produce flocculation of the colloid, extracting the colloid by a water-immiscible organic solvent comprising a chlorinated solvent, alcohol, ketone or hydrocarbon, and placing the resulting colloidal dispersion in contact with the aqueous Cs-containing solution.  The process can be used with advantage for decontaminating radio-active waste before it reaches a public sewage system.  More specifically, a colloidal dispersion of copper ferrocyanide and potassium ferrocyanide is prepared by mixing equal volumes of an aqueous copper sulphate solution (3 x 10-3 M) and an aqueous potassium ferrocyanide solution (2 x 10-3 M).  To 500 parts by volume of this dispersion are added 40 parts by volume of an aqueous cequartyl solution (laurylbenzyldimethyl-ammonium chloride)(5 x 10-3 M).  The colloid flocculates.  The flocculate is removed and dispersed in 10 parts by volume of dodecane to which 0.15 part by volume of lauric alcohol has been added.  The resulting colloidal dispersion is placed in contact with 10 parts by volume of an aqueous solution having the following composition: CsNO3 10-3 M, HNo3 0.26M and Ba(NO3)2 9gBa/1. After extraction 99.96% of the Cs has passed into the organic phase and only 0.04% of the original quantity remains in the aqueous phase.  An example is also given describing the separation of Sr from a radio-active solution.
