A molecularly imprinted polymer ion exchange resin for selectively removing one or more inorganic ions in a liquid medium is disclosed and described. The exchange resin can include a bead having a porous structure and comprising a cross-linked molecularly imprinted polymer having molecular sized cavities adapted to selectively receive and bind a specific inorganic ion in a liquid medium. A process for preparing a molecularly imprinted polymer ion exchange resin can include (a) polymerizing a polmerizable mixture in the presence of an inorganic ion imprinting complex to form a bead, said inorganic ion imprinting complex including a ligand and an inorganic ion; and (b) removing the inorganic ions from the bead to form the molecularly imprinted polymer ion exchange resin, the bead having a porous structure and comprising a cross-linked molecularly imprinted polymer having molecular sized cavities adapted to selectively receive and bind a specific inorganic ion in an liquid medium.

[FR] L'invention concerne une résine échangeuse d'ions en polymère à empreinte moléculaire servant à enlever sélectivement un ou plusieurs ions inorganiques présents dans un milieu liquide. La résine échangeuse d'ions peut comprendre des billes ayant une structure poreuse et comprenant un polymère à empreinte moléculaire réticulé ayant des cavités de taille moléculaire adaptées pour recevoir et fixer sélectivement un ion inorganique spécifique présent dans un milieu liquide. Un procédé servant à préparer une résine échangeuse d'ions en polymère à empreinte moléculaire peut consister à : (a) polymériser un mélange polymérisable en présence d'un complexe formant une empreinte d'un ion inorganique pour former des billes, ledit complexe formant une empreinte d'un ion inorganique comprenant un ligand et un ion inorganique ; et (b) enlever les ions inorganiques des billes pour former la résine échangeuse d'ions en polymère à empreinte moléculaire, les billes ayant une structure poreuse et comprenant un polymère à empreinte moléculaire réticulé ayant des cavités de taille moléculaire adaptées pour recevoir et fixer sélectivement un ion inorganique spécifique présent dans un milieu liquide.
