Abstract
A novel ion exchanger useful for universal ion-exchange purposes and, in particular, for ion exchanger for ion-exchange chromatography is proposed, said novel ion exchanger being obtained by introducing radicals of one or more ion-exchangeable groups into cross-linked glucomannan beads by a chemical treatment thereof. Such ion exchanger beads are superior in the compressive strength and permit a high flow rate of the liquid to be subjected to ion exchange through an exchange column packed with them.
