Abstract
Distribution coefficients and separation factors of rare earth elements (REE) were determined during extraction with an extractant based on Cyanex 272 and P507 in a diluent of 15% isooctanol in isopar L. Aqueous solutions of medium-heavy lanthanide chlorides were studied at their concentration in a solution of 0.05-0.9 g/dm3. A series of experiments were carried out with the concentration of the extractant in a diluent of 10, 20, 30 and 40 wt.%. Based on the data obtained, extraction isotherms were constructed, as well as graphical dependences of the distribution coefficients and separation factors
