摘　　要：综述了近来沸石和介孔分子筛吸附亚硝胺方面的新进展,论证了大体积亚硝胺在小微孔沸石上通过将官能团插进狭窄孔道的特殊吸附模式,研究了金属氧化物对于介孔分子筛材料的原位修饰,并展望了消除亚硝胺污染功能新材料的发展方向。Some latest research progresses in adsorption of nitrosamines by use of zeolites and mesoporous molecular sieves are reviewed. The selective adsorption of nitrosamines on zeolite, especially the inserting adsorption model of bulky nitrosamines on those zeolites with small pore size in which the N-NO groups insert into the zeolite channels, is introduced. The in situ modification of mesoporous molecular sieves with metal oxides such as copper oxide are introduced, which significantly promotes the selectively adsorption of volatile nitrosamines. Finally, the development of new functional materials to eliminate the pollution of nitrosamines is prospected.
