摘　　要：本文用配合沉淀和活性炭吸附相结合的方法，从高级富勒烯含量较高的混合物中，大量、快速分离Ｃ６０。An improved, large amount and rapid separation/purification method for C 60 was reported. The method is based on differential complexation of C 60 , C 70 and higher fullerenes with AlCl 3. The C 70 and higher fullerenes complexed much stronger with AlCl 3 and the resulting complexes precipitated out of the solution. The active carbon was added in the above solution to get rid of trace C 70 and higher fullerenes remained in solution of CS 2. In addition to pure C 60 (99.8%),C 70 enriched fullerenes mixture is gotten. The neutral fullerenes were identified by electrospray ionization mass spectrometry.
