The Dy endohedral C60 (Dy@C60) was extracted with aniline under ultrasonic irradiation from the soot prepared by arc-heating of Dy2O3/graphite composite rod under He pressure of 80 Torr. The purification of Dy@C60 was performed by using high performance liquid chromatography (HPLC) technique. Furthermore, the Dy endohedral C82 (Dy@C82) was effectively extracted from the soot with N,N-dimethylformamide (DMF).
