Complexation-ultrafiltration technique was efficiently used to achieve selective separation of nickel(II) and copper(II) ions from an aqueous solution operating in diafiltration mode. Nickel recovery in the permeate of 100% and copper recovery in the retentate of 94.39% were obtained by using the Iris 30 membrane at TMP of 2 bar. Obtained results show that formation of the metal–polymer complex is pH dependent and this is a key-point for the separation. The described methodology can be efficiently used to obtain selective separations by means metal bonding to water soluble polymers.
