英文摘要	Spherical particles (6-8 mu m) of magnesia-zirconia composite were prepared by means of sol-gel process. The composites were modified with 2,4,6-trinitrophenol and pyrenebutyric acid, respectively, and then used as charge-transfer stationary phases. The resulting stationary phases were characterized by elemental analysis, diffused reflectance FT-IR, nitrogen adsorption analysis and solid state NMR. The separation Of C-60, C-70 and higher fullerenes was investigated on the two stationary phases. The influence of the mobile phase (toluene-cyclohexane) with different composition and the column temperature on the separation Of C-60 and C-70 was examined, respectively. The retention time of C-60 and C-70 on the two stationary phases increases with decreasing toluene content in the mobile phase or with increasing the column temperature. Higher fullerenes can be separated well at 90 degrees C using toluene as the mobile phase on the 2,4,6-trinitrophenol modified magnesia-zirconia. Based on the results of column loading capacity test, the magnesia-zirconia modified with 2,4,6-trinitrophenol and pyrenebutyric acid are probably considered as potential materials for the separation of fullerenes in large amounts.
