It was found that the sorbents have complex porous structure and contain macropores, mesopores (3-6 nm), as well as micropores. It was shown that increasing the carbon content of mineral-carbon sorbents affects the pore size distribution. A correlation between the volume of mesopores and C fullerene output in the process of chromatographic separation of fullerenes in toluene in the gravity mode was determined |
