anion-exchange resin

an·i·on ex·change

(an'ī-on eks-chānj'), The process by which an anion in a mobile (liquid) phase exchanges with another anion previously bound to a solid, nonmobile, positively charged phase, the latter being an anion exchanger. For example, the process takes place when Cl^- is exchanged for OH^- in desalting. The reaction is Cl^- (in solution) + (OH^- on anion exchanger⁺) → (Cl^- on anion exchanger) + OH^- (in solution); in combination with the cation exchange, NaCl is removed from solution. Anion exchange may also be used chromatographically, to separate anions, and, medicinally, to remove an anion (for example, Cl^-) from gastric contents or bile acids in the intestine.
