Until now,column chromatography is still the chief method for separation andpurification of C<sub>60</sub>/C<sub>70</sub>.The stationary phases used in the method can either be neutralalumina,graphite,activated charcoal,or the mixture of activated charcoal and silicagel,etc.The method that uses neutral alumina as the stationary phase and hexane asthe mobile phase is the most popular and earliest used,but it has many limitations.
