为了开辟沸石在生命科学中的新应用，制备了用于抗癌斗争的分级沸石。研究了碱处理的MFI分子筛在pH = 1.2的人工胃液中对挥发性亚硝胺N-亚硝基吡咯烷（NPYR）的吸附。碱处理后的样品通过在分子筛中形成中孔来加速传质，其吸附能力均高于HZSM-5分子筛，吸附平衡数据符合Freundlich方程。
To open a new application of zeolite in life science, hierarchical zeolites were prepared for the struggle of anti-cancer. Adsorption of N-nitrosopyrrolidine (NPYR), one of the volatile nitrosamines, by alkaline-treated MFI zeolite in artificial gastric juice with pH of 1.2 was investigated. Through the creation of mesopores in zeolite to fasten mass transport, all alkaline-treated samples exhibited higher adsorptive capability than HZSM-5 zeolite, and the equilibrium adsorption data could be fitted to the Freundlich equation.
