Publication number: 20230015254Abstract: 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.Type: ApplicationFiled: December 3, 2020Publication date: January 19, 2023Inventors: Jean-Claude LEPRETRE, Jonathan DESEURE, Fannie ALLOIN, Clémence YVER
