The strong adsorption of zeolite Y and ZSM-5 for N-nitrosamine such as N-nitrosodimethylamine and N-nitrosopyrrolidine was firstly revealed by use of adsorption, temperature programmed surface reaction and TG-DTA techniques. Zeolite can adsorb N-nitrosamines without interference of organic solvent, which will be helpful for removal of the N-nitrosamines pollution in environmental protection.
