摘要：

Cerium oxide (CeO2) was tested as a packing material in liquid chromatography for the separation of C-60 and C-70 fullerenes. The separation of C-60 and C-70 fullerenes could be achieved within 20 min by using pure n-hexane as the mobile phase. Furthermore, some higher fullerenes could also be separated in less than 40 min. The peak area was reproducible to a large extent. The separation of fullerenes by liquid chromatography on CeO2 is shown to be an effective method for their isolation in large amounts. The column efficiency of the CeO2 column was compared with commercial silica gel and ODS columns. The main advantage of the CeO2 column is its ability to separate large amounts of fullerenes (C-60 and C-70) in toluene.
