Abstract

Procédé de séparation sélective d'un métal cible présente dans une solution aqueuse, par mise en contact d'une solution aqueuse contenant un métal cible avec une solution aqueuse contenant un polymère hydrosoluble capable de se lier au métal cible pendant suffisamment de temps, ce qui permet de former un complexe hydrosoluble polymère/métal cible, et par séparation de la solution contenant ledit complexe de la solution.
