It has been observed that in cases where the water present is not sufficient for complete hydration of all Nd ions, the aqueous and alcohol molecules jointly solvate the rest of the Nd ions. From the absorption spectra of neodymium chlorite alcohol-aqueous solutions it appears that alcohol molecules are not displaced completely from the Nd ion solvate sheri by water molecules even when 20 to 30 water molecules per one neodymium chloride molecule are added to the alcohol solution. Some considerations are offered to show why the ratio of water molecules to salt molecules should be so high for a complete displacement of alcohol by water in the NdH ion solvate shell. (tr-auth) A new and rapid method for the liquid-liquid extraction of U and Pu from HCl solution is based on the use of tri(iso-octyl)amine dissolved in xylene or methylisobutylketone. Uranium and/or Pu are separated from Th, alklis, alkaline earths, rare esrths, Zr, Nb, Ru, and other elements which do not form anionic species under the conditions described. The technique may be used for either tracer or macro quantities of U. Several practical applications of the method for the separations chemist are proposed. (auth)
