Adsorption of L-Histidine onto Functionalized Mesoporous SBA-15 Organosilicas

Abstract: Adsorption of L-histidine (LH) over mesoporous SBA-15 silicas functionalized by amine-, thiol-and cyano-functional groups has been studied. These organosilicas have been synthesized by co-condensation of proper monomers in the presence of a template (Pluronic P-123), and characterized by elemental analysis, nitrogen adsorption, X-ray diffraction and transmission electron microscopy. The highest LH static adsorption capacity was observed for the cyano-functionalized sample [approximately 70 mg g -1 (450 mol g ). Show more

“…However, the undoubted advantage of this material is the presence, apart from the hexagonally arranged mesopores, of significantly smaller pores that account for more than 70% of the surface area of this material. These micropores are located in the walls of this type of material and are a combination of ordered main pores [32]. The advantage of SBA-15 is not only the unique construction of this material and better stability of its structure but also the possibility of a safe application of this material because it does not exhibit toxicity.…”

“…So far many functional groups have been used to modify the silica surface by both one-pot co-condensation and post-synthesis grafting including amine [16][17][18][19], cyano [20,21], thiol [2,[22][23][24], vinyl [25][26][27], phenyl [20,26,28], alkyl [29][30][31][32] and many others. Some studies have also focused on the functionalization with carboxylic groups [33][34][35][36][37][38].…”
