自从Kratschmer等人报道了宏观量富勒烯(Fullerene)的制备方法以来,国内外又有许多科学家相继发表了一些改进方法,这些方法都能生产克量级的C_(60)和C_(70)的混合物.由于C_(60)和C_(70)性质相差不大,分离起来比较困难.文献报道方法主要有高压液相色谱料(HPLC)和以中性氧化铝、石墨、活性碳等为填料的柱色谱法.这类方法主要都是利用C_(60)和C_(70)的物理性
Since Kratschmer et al. Reported on the macroscopic preparation of fullerene, many scientists at home and abroad have published some improvement methods in succession, which can produce grams of C 60 and C 70 in the order of magnitude. (C 60) and C 70 (70), and it is difficult to separate them.High pressure liquid chromatography (HPLC) and using neutral alumina, graphite and activated carbon as fillers Column chromatography.These methods are mainly the use of C_ (60) and C_ (70) of the physical
