An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them where the tr… WebThe ligand coupled to the resin surface allows electrostatic interactions as well as hydrophobic interaction, hydrogen bonding, or thiophilic interaction. The different possible interaction modes give the resin novel selectivity and and make it salt tolerant.
