The extraction and separation of five different rare-earth elements, La, Nd, Eu, Dy Yb, from an aqueous chloride solution non-aqueous solutions using the solvating extractant Cyanex 923 was investigated. As previous studies had demonstrated potential solvent (NASX) to refine rare earths ethylene glycol, structural analogues glycol (1,2-propanediol 1,3-propanediol) other polar organic solvents (...
