Abstract

Abstract: The defect voids in the wall of mesoporous silica increase the contact probability of N-nitrosopyrrolidine (NPYR) with the active sites and retain high freedom degrees of target adsorbed, which lead to the higher adsorptive efficiency in comparison with normal mesoporous aluminosilicates.

Key words: mesoporous MCM-41, pore wall&rsquo, s structure, structural defect, nitrosamine, adsorption
