실험 절차

In accordance with the present invention a sodium cation form of zeolite A is prepared from natural clinoptilolite by a novel two step hydrothermal process which comprises (1) heating the natural clinoptilolite in an aqueous sodium hydroxide solution for a period of time to dissolve clinoptilolite and filtering to remove undissolved material, including undissolved clinoptilolite and, elemental impurties, and form a filtrate which is (2) reacted by heating with at least 75 percent of a stoichiometric amount of sodium aluminate in aqueous solution for a period of time to precipitate and form zeolite A which may be recovered by filtration of the mixture followed by water wash and drying.
