| Abstract: | Nitrosamines are well-recognized carcinogens,and nitrosamines in smoke causes health hazard by smoking.How to adsorb and catalytically degrade nitrosamines in the environmental tobacco smoke with complex composition becomes the challenge facing zeolite material.In this article some latest research progresses in adsorption and catalytic degradation of nitrosamines by zeolites are reviewed.The special selectivity of zeolite toward nitrosamines and the degradation of nitrosamines by zeolite are described,and how to elevate the efficiency of zeolite with metal compounds modification is introduced.Also,the research progress on the removal of nitrosamines is summarized.Finally the development of new functional materials to eliminate the pollution of nitrosamines is prospected. |
