chelating polymer
Polymer containing ligand groups capable of forming bonds (or other attractive interactions) between two or more separate binding sites within the same ligand group and a single atom.
Chelating polymers mostly act as ion-exchange polymers specific to ions that form chelates with chelating @L03518@ of the polymer.
