摘要：

To open the new application of zeolite in health care as the capturer of nitrosamines in gastric juice, capture of N'-nitrosonornicotine (NNN) in aqueous solution by the acid-immerged zeolite is investigated in this article for the first time, facing the challenge arising from the acid immersion on the structure of zeolite and the selective adsorption. Several zeolites with different Si/Al ratios and pore structures, including NaY, ZSM-5 and MCM-22, are employed to study their structure variation after the acid leaching in the solution with the same pH value as that of gastric juice. Apart from the characterization of XRD, XRF, ICP, SEM and nitrogen adsorption-desorption methods, these samples are assessed to adsorb the NNN in aqueous solution. According to the results, the zeolites with Si/Al ratio of about 13 can keep their adsorption performance after acid treatment, rather, those with the Si/Al ratio of around 10 show the enhanced adsorption capability in deed. Besides, human 293-T cells are utilized to monitor the actual function of zeolite in selectively trapping NNN in aqueous solution, in order to select zeolite for new application in health care.
