Abstract
Porous granules that contain separate particles of alkali metal silicate and zeolite are stable and are efficient ion exchangers in aqueous effluents and/or solutions. Said granules are heated to provide the stability required so that even though some silicate may dissolve when the granules are exposed to water, the zeolite does not disperse throughout the water.
