The method as claimed in claim 1 wherein said water is placed within an ostomy pouch. It is a solution of ammonia gas (a compound of nitrogen and hydrogen) in water. After about 2.5 hours, under these conditions, very little additional ammonia is adsorbed onto the sorbent material. The adsorbed material can be stored safely until ready for use. May be subject to detonation if allowed to dry out. A method for manufacturing the type A molecular sieve is disclosed in U.S. Pat. Manufacturing process of ammonia • Introduction • In large scale commercial ammonia production plants, the feedstock which makes up the reactants are water, methane and air. During this charging period, the ammonia gas adsorbs onto the sorbent material 7, effectively immobilizing the ammonia gas onto the surface of the molecular sieve. The loaded sorbent can be placed into the plastic bag along with some water, the used ostomy pouch or other item is then placed into the pouch. From the work completed, it appears that 13 x 1/16" pellets yield the best results, as seen in the above data. It is important, however, to minimize the presence of water in the gas or mixture of gasses during the adsorption process, since water will adsorb preferentially to ammonia in most cases. In case of spillage, the loaded sieve will not irritate dry skin. FIG. A slower release rate would further enhance the safe handling aspects of the loaded sorbent. The dissolution time of the used ostomy pouch constructed of Estane X-4655 plastic material, with a wall thickness of 0.004 inches is then very rapid (about 3 minutes). There are literally dozens of large-scale ammonia production plants throughout the industrial world, some of which produce as much as 2,000 to 3,000 tons per day of anhydrous ammonia in liquid form. FIG. Ammonia serves as a catalyst in the production of some synthetic resins. Water can be added to the inside of the pouch, and the pouch can then be sealed off.
