| Abstract: | 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. |
