Abstract: The zirconia-alumina composites, prepared by means of sol gel process, were modified with 2, 4, 6-trinitrophenol and used as π-acidic stationary phases for the separation of C60and C70. The influence of the mobile phase(toluene-cyclohexane) composition, the column temperature and the different flow rates on the separation of C60and C70was examined. At the same time, the effect of the composites, which were treated and untreated with nitric acid, on the separation was also investigated. The results show that the acid-treated zirconia alumina composite, after being modified with 2, 4, 6-trinitrophenol, exhibits advantage in the separation of C60and C70, and is a potential packing material for separation of fullerenes in preparation scale.
