A process of selectively separating a target metal contained in an aqueous solution by contacting the aqueous solution containing a target metal with an aqueous solution including a water-soluble polymer capable of binding with the target metal for sufficient time whereby a water-soluble polymer-target metal complex is formed, and, separating the solution including the water-soluble polymer-target metal complex from the solution is disclosed.

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.
