Effective Separation of Fullerene Mixture by Sorbent on The Base of Aluminium Oxide

In this paper the results of synthesis and investigate of novel sorbent on the base of aluminium oxide with carbon cover are presented. It was established that application of concentrate fullerene solution on the oxide aluminium powder and following annealing allowed to synthesize sorbent with the surface which is density cover by carbon. The structure of aluminium oxide after annealing does not change signiёcantly according to RFCA data. It was established by XPS method that molecules of С60 chemically bonded with aluminium oxide are presented at the carbon cover. There are oxygencontaining groups and amorphous carbon on the sorbent surface. The test of using sorbet show the effective extraction of С60 and С70 from the fullerene mixture by single stage separation: С60 with purity 98 % and С70 with purity 70 %.
