Mixtures of materials including solutions, gaseous mixtures, and colloids are purified or separated by contact with or passing through ion exchange or permselective materials which have been modified by polymer deposition or graft polymerization. The materials used in the separatory process are generally webs, membranes, beads, granules, or other shaped objects which have ion exchange capacity or permselective surface characteristics, which materials have been modified by graft polymerization or polymer deposition to provide the desired permselective or ion exchange characteristics.
