https://doi.org/10.1351/goldbook.A00360

Definition:
ion exchanger with anions as counter-ions. The term anion-exchange resin may be used in the case of solid organic polymers. The base form of an anion exchanger is the ionic form in which the counter-ions are hydroxide groups (OH– form) or the ionogenic groups form an uncharged base, e.g. –NH.
