Synthesis and Adsorption Characters of Silica Hollow Spheres

摘要：

　　A kind of ordered meso-sized hollow silica spherical material was prepared by hydrothermal route using monodispersed cross-linked polymethyl polymer spheres as template,metacrylate tetraethyl orthosilicate as a silica source.The calcination was empolyed for the removing of template and generation silica hollow spherical materials with meso-sized pores.The adsorption performance of the obtained hollow silica spheres was investigated and the results indicated that the obtained hollow silica spheres had high adsorption capacity for sulfadimethoxine.They were sucessfully used as the dispersive adsorbent for matrix solid phase dispersive extraction sulfadimethoxine from chicken tissue with satisfactory results.
