| 1996 | Invention patented by Mark W. McGlothlin on April 22th, 1996. Abstract: A method of producing ammonia water (aqua ammonia) by means of desorbing an ammonia laden sorbent, preferably a zeolite molecular sieve or silica gel into water. The method includes placing an activated sorbent material into a sealed vessel, such as a pressure pot, and exposing it to ammonia gas for a period of time. After loading by exposure to ammonia gas, the loaded sorbent is then placed into an air and water tight container for storage. The pouch can be stored for extended lengths of time prior to use of the contents. When ready for use, the contents of the pouch are dropped into a container of water. In one preferred use of the loaded sorbents, the container of water is a toilet bowl. In another preferred embodiment, the container is a separate disposal pouch, such as a small plastic bag capable of holding an ostomy pouch, sanitary napkin or incontinence pad. After use, the ostomy pouch or other device can be made to dissolve by placing the used pouch in ammonia water at a pH of 10.3 or higher. |
