The possibility of using mixtures of acetone and hydrochloric acid as eluants for the separation of rare earth elements was studied. The separation of the groups La-Ce-- Pr-- Nd, Sm-- Lu--Gd-- Tb--Dy-- Ho-- Er, and Yb--Lu was made at ordinary temperatures. The mixtures of organic solvents and mineral acids used as eluants permit, by their composition, the variation of two parameters: the concentration of the acid and the concentration of the solvent. The methods commonly utilized appear to demand a rigorous control of the pH and the temperature. After a distillation of the organic solvent, the separated elements are obtained as chlorides.
