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, the 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.
Possible applications are:
Trace enrichment by using chelating ion exchangers
Determination of total salt content of solutions and water by H+ exchange
Removals of interfering cations or anions
Chromatographic separation
Digestion of insoluble compounds
Application as a catalyst
