The Dy endohedral C<SUB>60</SUB> (Dy@C<SUB>60</SUB>) was extracted with aniline under ultrasonic irradiation from the soot prepared by arc-heating of Dy<SUB>2</SUB>O<SUB>3</SUB>/graphite composite rod under He pressure of 80 Torr. The purification of Dy@C<SUB>60</SUB> was performed by using high performance liquid chromatography (HPLC) technique. Furthermore, the Dy endohedral C<SUB>82</SUB> (Dy@C<SUB>82</SUB>) was effectively extracted from the soot with N,N-dimethylformamide (DMF).
