Comprehensive studies of sorption properties of carbon-base materials from sphagnum (peat) moss, namely, pyrolytic amorphous carbon and multiwalled carbon nanotubules, are described. The capacity of nanotubules for sorbing metal cations is determined. It is shown that the ability of nanotubules to undergo oxidative modification depends on their formation process parameters and their sorption capacity depends on the retention time. The feasibility of use of the obtained carbon-base materials as efficient enterosorbents is examined.
