ABSTRACT:
A process for the increasing of the capacity of kinetics limited ion exchange column wherein an ion exchange resin impregnated with an insoluble, inorganic compound is employed. Because of the increased kinetics and density of the impregnated ion exchange resin, flow rates of the ion-containing medium through the resin may be increased. In addition, the insoluble, inorganic compound often removes certain specific materials from the aqueous stream.
