摘要：

The synthesis of fullerenes was carried out using dc arc discharge technique. The separation and identification of higher fullerene C-84 was done by high performance liquid chromatography (HPLC). The raw soot collected from the high temperature region was dissolved in toluene and then toluene-extracted soot dissolved in n-hexane and kept in laboratory environment for more than one month. The peaks Of C-60 and C-70 along with C-84 were observed. The existence Of C84 was confirmed by using linear regression between capacity factor log [k'] and the carbon number. (C) 2008 Elsevier B.V.
