The disclosure relates to the field of metal ion capture, more particularly of selective capture of nickel Ni(II) ions, by a polymeric compound based on a polymer selected from styrenic polymers and chloropolymers. In the polymeric compound, at least one portion of the monomer units of the polymer is functionalised by the ligand, the ligand including at least one chemical group selected from the glyoxime groups.

The glyoxime groups have a strong affinity for the Ni(II) ions, as well as an excellent selectivity vis-à-vis metal ions of chemical properties similar to Ni(II) ions. This ligand thus allows a selective complexation of the Ni(II) ions by the polymeric compound, including in solutions of low concentrations of Ni(II) ions.

The polymeric compound according to at least one embodiment of the disclosure is particularly intended for capturing the Ni(II) ions during the electrogalvanising methods as well as for recycling material comprising nickel.

An ion exchanger filter device has a housing with inflow opening and outflow opening for a medium that penetrate a wall of the housing. An ion exchanger cartridge is arranged in the housing. A flow path for the medium extends from inflow opening through the ion exchanger cartridge to outflow opening. The ion exchanger cartridge has a cartridge container with a receptacle that is delimited by a circumferentially extending wall provided with one or more outflow ports distributed circumferentially about the circumferentially extending wall. The receptacle is filled with ion exchanger material. The outflow ports, relative to the outflow opening, are arranged offset in axial direction of the ion exchanger filter device. The flow path has a deflection downstream of the outflow ports. The outflow ports, relative to a direction of gravity in intended mounting position of the ion exchanger filter device, are arranged axially above the outflow opening.
