Abstract
A ferromagnetic material is integrally incorporated with each of the ionic beads of one component of a mixed ionic resin bed containing more than one ionic bead component, such that the one ionic bead component can be separated from the other component by attraction to a magnetic field. Ionic beads containing a ferromagnetic material are attracted to an inhomogeneous magnetic field while other ionic beads devoid of the ferromagnetic material are not so attracted. In another embodiment, a ferromagnetic material having a specific Curie temperature may be incorporated with one ionic bead component while the other bead component contains a different ferromagnetic material having a different Curie temperature.
