This article discusses adsorption of water and benzene vapour in mesoporous materials (mesoporous silica MCM-41 MCM-48 and their modification).MCM-41 and MCM-48 were synthesized Hydrothermally at 100C using cethyltrimethylammonium chloride or dodecyltrimethylammonium bromide for MCM-41 (C16) orMCM-41 (12) respectivelyand a mixture of cethyltrimethylammonium bromide and Triton X-100 for MCM-48 as templates. their modification were conducted by silylation of MCM-41 (C16) and MCM-48 with trimethylchloro silane (MCM16-TMCS and MCM48-TMCS) and t-butyldimethylchloro silane (MCM16-TBDMCS and MCM48-TBDMCS). Resultsshowed that MCM-41 and MCM-48 materials had hydrophobic features which were shown in the small amount of water adsorption at low P/P. The hidrophobicity of samples used in this study decrease in the sequence MCM41 (C16) MCM-48 MCM-41 (12). The hydrophobicity increased when MCM-41 and MCM-48 were silylated with TMCS or TBDMCS. All unsilylated MCM matewrials show higher affinity to benzene at low P/P than thesilylatedsamples. The result of water and benzene adsorption showed that silylated samples are promissing candidates as selective adsorpbents for organic compounds.
