A variety of characterizations demonstrated that the silica products exhibited well-formed spherical morphology, ordered mesostructure, narrow pore size distribution and large surface area (~700m2g−1). It was found that the synthesized OMSs had high adsorption capacity by using oxymatrine as model solute. The column packed with the silica spheres exhibited low back pressure and baseline separation of aromatic compounds such as benzene and nitrobenzene could be achieved. These results demonstrated the synthesized OMSs as a potential stationary phase for liquid chromatography.
