FULLERENE-CONTAINING ACTIVATED COAL-BASED SORBENT Russian patent published in 2008 - IPC B01J20/20 

Abstract RU 2322288 C1

FIELD: carbon materials.

SUBSTANCE: invention provides sorbent for sorption of organic substances, heavy metals, and microflora from water and aqueous solutions, which sorbent is based on activated carbon and contains fullerene in amount 1 to 100 μg/g activated carbon. Sorbent production process involves treatment of activated carbon with aqueous solution containing fullerene and stabilizer belonging to group including crown ethers, cyclic diethers, ethylene glycol or propylene glycol trimers and tetramers, mono- and diethers of indicated trimers and tetramers with C1-C6-alcohols, calixarenes, and mixtures of these compounds.

EFFECT: improved quality of purification of aqueous solution.
