ABSTRACT:
An ion-exchange composition comprising a substrate of a macroporous synthetic resin having ion-exchanging sites at least on its available surface; and finely divided, synthetic resin particles having a volume average diameter less than 0.1 micron and greater than about 0.005 micron and having, at least on their outer surfaces, ion-exchanging sites which attract the ion-exchanging sites of the substrate, irreversibly attached as a monolayer to the available surface of the substrate. The composition is used for removal and separation of ions, and is especially useful in liquid ion-exchange chromatography.
