Abstract
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.
