Recent advances of mesoporous materials in sample preparation

Review of the use of mesoporous silicas for removing dye from textile wastewater

“…For example, MCM-41 prepared using cationic cetyltrimethylammonium (CTA) surfactants, after calcination yield a hexagonally ordered porous solid with uniform pore sizes of 20 to 30 Å (Ying et al 1999;Ogawa 2002;Øye et al 2006). There are various physical and covalent strategies for functionalizing MPSs, such as co-condensation (one-pot synthesis), grafting (post-synthesis modification) and imprint coating (Vinu 2005;Slowing et al 2008;Zhao et al 2012). Co-condensation of a tetraalkoxysilane and one or more orgaoalkoxysilanes has been widely used for producing inorganic-organic hybrid networks.…”

Evaluation of bi-functionalized mesoporous silica for solid-phase extraction of twelve endocrine disrupting compounds from water

“…In that sense, investigation and application of new materials has become a very interesting research area in field of Analytical Chemistry [1,2]. For example, a great range of new mesoporous materials are gaining interest in sample preparation because of their desired characteristics: (a) highly ordered and size-controlled mesoporous structures, (b) extremely high surface areas and large pore volumes, (c) very good thermal and chemical stability and (d) high flexibility in functionalization to enable the introduction of hydrophilic, hydrophobic, polar as well as charged functional moieties on surface [3].…”

Facile synthesis of magnetic mesoporous titania and its application in selective and rapid enrichment of phosphopeptides

“…However, the difficulty in collecting mTiO 2 from their dispersing media could cause inconvenience in its practical application [5]. Thus, some efforts have been directed toward decorating mTiO 2 with magnetic nanoparticles (MNPs) so that the resultant composite has high capacity in the capture of phosphopeptides and can be separated easily from digest mixture of phosphoprotein [6,7]. Unfortunately, complicated experimental processes were generally necessary when employing conventional methods including impregnation, coating, doping methods, and so on.…”
