亚硝胺是公认的致癌物质，本文综述了近年来沸石吸附和催化降解亚硝胺的研究进展，介绍了沸石对亚硝胺的特殊选择性以及沸石对亚硝胺的催化降解作用，并对沸石吸附和催化降解亚硝胺的机理进行了初步探讨。介绍了分子筛的概况，介绍了如何通过金属化合物改性来提高分子筛的去除效率，总结了分子筛去除亚硝胺的研究进展，最后展望了消除亚硝胺污染的新型功能材料的开发。
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.
