摘要：

Porous micrometer titania microspheres for HPLC packing were prepared by sol-gel method with titanium isopropoxide (Ti(OPri)(4)) as titanium source. The effects of some factors including H2O, hydrochloric acid (HCl), and acetic acid (HAc) concentrations on the shape, diameter, gelation time, and specific surface area of the titania microspheres were discussed. The obtained titania microspheres were characterized by SEM and BET measurements. The results show that titania microspheres were mostly regular-ball with 5 mu m average particle size, 60.31 m(2)/g surface area, 0.068 mL/g pore volume, and 5.18 nm average pore diameter.
