Abstract: Isotherms for the sorption of light fullerenes (C$_{60}$ and C$_{70}$) from toluene solutions with the use of multiwall carbon nanotubes (MWCNTs) were investigated. Both isotherms are of the Langmuir-type. The successful liquid chromatographic separation of light fullerenes from toluene solutions was accomplished using the above-mentioned sorbent.

Keywords: light fullerenes, C$_{60}$, C$_{70}$, isotherms of sorption, toluene solutions, chromatographic separation.
