In general, ion exchangers consist of a cross-linked polymer matrix with a uniform distribution of fixed ionic groups sited throughout the resin structure. These must be balanced by a similar number of ions of the opposite charge, (counter ions) to maintain electrical neutrality. Cation exchangers therefore, exchange and enrich only cations, anion exchangers only anions. In contrast adsorber resins have a non ionic, but depending on the structure, a somewhat polar character, and don't adsorb stoichiometrically both: anions, cations, as well as uncharged compounds.
