摘要：
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(-1))]; by contrast, pristine SBA-15 had a lowest adsorption capacity of approximately 25 mg g(-1) (170 mol g(-1)).
