Filtering materials based on multi-walled carbon nanotubes for purification of liquids

Deposition of multi-walled carbon nanotubes on the hollow cylindrical substrates in the synthesis method MOCVD leads to macrocylinders with the walls of oriented arrays of carbon nanotubes. The processes of fluid flows through the macrocylinders modified by the polymer have been studied, as well as their filtering ability in relation to heavy metal ions and oil products. Functionalization of the nanotube surface by carboxyl and hydroxyl groups has been carried out, the sorption properties of materials have been investigated.
