Abstract
The invention relates to a poly(ether-phosphoramide) polymer, in which a repeating unit comprises an isosorbide unit and a phosphoramide function, and which exhibits a high affinity for rare earth elements, particularly lanthanum and cerium. This polymer is especially useful for extracting a rare earth element from an aqueous liquid medium containing it, such as a mining effluent, using a solid-liquid extraction process.
