Original Abstract Submitted

A method for extracting at least one lanthanide element, preferably selected from lanthanum (La), praseodymium (Pr), neodymium (Nd), europium (Eu), dysprosium (Dy), and ytterbium (Yb), from a solid material including the lanthanide element, one or more waste elements such as iron (Fe), and/or one or more other lanthanide elements. The method implements a composition including water, at least one organic aprotic solvent, and at least one charged hydrotrope. Also, the use of the composition for recycling lanthanide elements, and more particularly WEEE, and for the decontamination of effluents.
