Abstract

L'invention concerne un procédé d'extraction (210) d'ions phosphore de solutions, qui consiste à adsorber les ions phosphore dans un entraîneur et à libérer les ions phosphore dans un éluat pendant la régénération (230) de l'entraîneur. La régénération (230) est assurée par de l'ammoniac. Les anions phosphate sont précipités (262) de manière qu'ils forment du phosphate de triammonium lors de l'introduction (260) de quantités excessives d'ammoniac. L'ammoniac restant dans la solution après la précipitation du phosphate de triammonium est réutilisé (266) pour régénérer l'entraîneur.
