烟草特有亚硝胺(TSNA)属于强致癌物,是吸烟导致癌症的重要因素.如何在成分复杂的环境烟气里吸附亚硝胺成为环境保护的难题.文章综述了近年来的研究进展,剖析了分子筛形貌对TSNA吸附的影响,讨论了液相吸附TSNA的新材料,并展望特定分子筛新材料的发展方向.
Tobacco specific nitrosamines (TSNA) are well-recognized carcinogens, and TSNA in smoke causes health hazard by smoking. How to adsorb TSNA in tobacco smoke with complex composi- tion becomes the challenge facing environment protection. In this article some latest research progress in adsorption of TSNA by new molecular sieves are reviewed. The special effect of molecular sieves morphol- ogy on the adsorption of TSNA in tobacco smoke is described, and the new functional adsorbents to trap the TSNA in aqueous tobacco extract solution are introduced. Finally the development of new functional materials to eliminate the pollution of TSNA is prospected.
