Abstract Germanium extraction has been studied using ion-exchange process thanks to polymeric resins. The ion-exchange resins have been prepared from catechol and with admixture with 8-hydroxyquinoline by alkaline polycondensation with formaldehyde. The polymeric resins were characterized and involved in sorption experiment. The selectivity sorption of germanium was studied in the presence of elements such as silicon, zinc or copper which are likely to be competitive cations in solutions from urban mines or mine deposits. Selective extraction and separation of germanium have been demonstrated. Changes in the selectivities properties of the resins have been observed through the incorporation of 8-hydroxyquinoline in the catechol matrix.
