ABSTRACT:
This invention relates to reactive groups immobilized on inorganic substrates such as derivatized glass, silica, ceramics, or metals. The immobilized reactive groups can be used to inactivate or remove nitrosating agents in liquids, thereby reducing the formation of potentially carcinogenic nitrosamines and nitroso compounds in liquids that come into contact with humans. The use of inorganic substrates provides several advantages, which include extending the range and adaptability of the method of this invention and allowing its use in liquids that would dissolve or react with organic polymers.
