发明名称 PROCEDE DE SEPARATION DE METAUX TELS QUE LE ZIRCONIUM ET L'HAFNIUM
摘要 The invention concerns a method for separating a metal (1) from a metal (2), preferably zirconium from hafnium, which consists in dissolving said metals in an aqueous solution wherein said metals are in a state preventing them from passing through a nanofiltration membrane; treating the aqueous medium with a ligand, for example EDTA, which is complexed with metal (1) and/or metal (2), then in passing the resulting treated medium on a filtering membrane allowing through the ligand-metal complexes, but retaining the metals not complexed with the ligand.
