Abstract
A granule comprises an inner core, which is formed from a material which does not expand appreciably in the presence of organic compounds, and an outer shell formed from an organo-clay which is preferably held on the inner core with the aid of a binder. The granule can be prepared by tumbling a particle of the inner core material in admixture with a powdered organo-clay and a binder therefor. A particulate bed of the granules can be used for separating organic compounds from a mixture thereof with an aqueous medium.
