SEPARATION OF C-60/C-70 MIXTURE ON ACTIVATED CARBON AND ACTIVATED CARBON-FIBERS

The possibilities for preparative separation of fullerene (C-60/C-70) mixture by flash chromatography on activated carbon or activated carbon fibres as a stationary phase are shown. The effect bf the nature of the activated carbon and of its specific surface area on the elution time, chromatographic peak width, amount, and purity of the recovered product (C-60 or C-70) was studied. Different possibilities for diminution of the quantities of the stationary phase and the eluent and of the duration of separation are described.
