摘　　要：利用自制的电弧炉，通过电弧放电法合成了内嵌金属富勒烯Gd@C82，研究并获得了制备钆金属富勒烯的最佳工艺条件：摩尔比Gd：C=1：15，电流I=90～100A，氦气压力0．08MPa；探讨并获得了Gd@C82新的萃取分离条件：常温下以DMF为溶剂，抽真空至压强为0．01MPa下萃取；讨论了内嵌金属富勒烯的生成和分离机理。MetaLlofullerenes Gd @ C82was prepared by arc-discharge, and its best technological conditions were obtained ： MGd ： MC = 1 ： 15, current I = 90 - 100A, helium pressure 0.08 MPa. Extraction and separation conditions of metallofullerenes were studied, the soot was extracted in vacuum with DMF as the solvent at room temperature. And generation and separation mechanism of endohedral metallofullerenes were discussed.
