| 摘 要： | 以氧氯化锆水解得到溶胶,然后以Span－80和Tween－85混合非离子表面活性剂为乳化剂、环己烷为有机相制成W／O型乳状液,用其控制粒度,可得到2～10μm的ZrO2凝胶微球。通过比表面积、孔容、孔径测试及对6种不同性质的物质的吸附试验表明,该微球产物可作为高效液相色谱填料。

| Abstract: | Zirconia sol was prepared by dissolving zirconyl chloride in water, and the sol formed gel in water/cyclohexane W/O style emulsion to obtain monodispersed particles of ZrO2(2-10 microns). After being washed and classified, the zirconia particles (3-5 microns) were collected and calcined at 800 degrees C to remove the organic residues on the surface of the particles. The mean pore diameter, specific surface area and specific pore volume of the zirconia particles were found to be 14.2 nm, 11.2 m2/g, and 0.04 cm3/g, respectively, by means of the BET method. The adsorption behavior of various organic compounds on the ZrO2 shows it will be useful as a column packing material for high performance liquid chromatography. |
