| 英文摘要 | The uniform titania nanoparticle multilayers/micrometer-sized silica particle(tio2/sio2) have been fabfabricated by consecutively assembling of surfactant c12h25so4na(sds) and titanium dioxide nanoparticles onto sio2 micro beads and subsequently removing the surfactant by calcinations. the specific surface area, total pore volume, and average pore diameter of tio2/sio2 are 202.1 m(2)/g, 0.3628 cm(3)/g and 7.0 nm, respectively. this titania supports was used to separate basic molecules, acidic molecules and non-basic isomeric aromatic mixtures under normal-phase conditions and compared with that of zirconia supports. it is shown that this enables the purification of basic fine chemicals and aromatic substances. the material exhibits good permeability, low back pressure, so it is an ideal packing for high performance liquid chromatographic applications. |
