Abstract
1482169 Ion-exchange ROHM & HAAS CO 24 Dec 1974 [27 Dec 1973 9 Oct 1974] 55536/74 Heading B1J A process for removing ions from liquid containing at least one metal salt comprises contacting the liquid with thermally regenerable hybrid resin to absorb metal salt and regenerating the hybrid resin by contact elution with an aqueous fluid at a temperature greater than that of the treated liquid at the time of its contact with the resin. By "hybrid" resin is meant a crosslinked macro-reticular host polymer the pores of which contain a separately formed crosslinked filling polymer. In Examples the host polymer is a weakly basic resin and the guest polymer a weakly acidic resin. The regenerant in some Examples is deionised water and in others water containing salts in one-half the concentration of the water being deionised.
