摘要：This paper presents several carbon materials (graphene, thermally expanded graphite, fullerenes, fullerene black), which are widely used in various areas of science and technology. Carbon materials are extensively used for water purification. Here we describe graphene-based nanocomposites which are used for sorption of heavy metals from water and for sorption of tetracycline from human body. We also describe composite materials based on thermally expanded graphite, which are highly effective for water purification from heavy metal ions and oil products. We provide examples of shungite with fullerenes usage for water purification and disinfection. We created sorption materials in the form of granules which consist of chitosan and carbon dopants. Carbonized millet threshing waste and fullerene black were used as carbon dopants. It was shown, that 10% additive of fullerene black increases mechanical integrity of the obtained granules and possesses almost the same properties as activated carbon of different grades. The following properties of the obtained sorption materials were determined experimentally: efficiency of model waste water purification from iron (III) cations; sorption capacity for iodine and methylene blue. It was shown, that carbon dopants (carbonized millet threshing waste and fullerene black) possess hydrophobic properties.
