【Abstract】 Zeolites can selectively adsorb N-nitrosamines and N-nitrosodimethylamine (NDMA) and N-nitrosopyrrolidine (NPYR) in gaseous phase can be adsorbed on zeolite NaY,ZSM-5 and NaA.The absorption was quite strong so that all of the adsorbed carcinogens cannot desorb or decompose from the zeolite until the temperature is increased above 523 K.The application of zeolite additive in new-type of cigarette was also explored in this paper.Both taste and the physical properties of cigarette were confirmed to keep unchanged.After added zeolite in the cigarette,the amount of tobacco special N-nitrosamines (TSNA) was significantly reduced in either side-stream or main stream,which was beneficial for protecting the health of both smoker and non-smokers at the same time.更多还原
