摘　　要：目前碳纳米管的纯化方法很多,有物理法、化学法和物理化学综合法等,然而这些方法仍不能得到高纯度的碳纳米管。色谱法分离纯化碳纳米管已成为近年来研究的热点,该法不仅能高效分离得到高纯度的碳纳米管,而且还能达到长短分离,具有重要的学术和实际意义。已报道的色谱纯化碳纳米管主要有空间排阻色谱以及毛细管电泳法,本文对上述色谱法纯化碳纳米管做了详细介绍。Although there are many initial separation methods for carbon nanotubes like physical, chemical and physical-chemical ways, high pure carbon nanotubes can＇t be obtained yet. However, most forms of carbon nanotubes are insoluble in solvent, which need to be stabilized dispersions. Chromatography is attractive as a method of separation power. Now, the chromatographic purification of nanotube methods are mainly size exclusion chromatography and capillary electrophoresis. The isolation of carbon nanotubes using chromatographic methods results in not only purification but also separation of nanotubes with different lengths and diameters. In this review, the methods for this purpose are introduced in detail.
