Isotherms for the sorption of light fullerenes (C60 and C70) 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, C60, C70, isotherms of sorption, toluene solutions, chromatographic separation.
