“…Today, carbon sorbents have been produced from a variety of carbon-containing raw materials: wood and cellulose (Malikov et al, 2007), coals (Drozdnik, 1997), peat (Novoselova et al, 2008), petroleum and coal pitches (Pokonova, 2001), synthetic polymeric materials (Mui et al, 2004), liquid and gaseous hydrocarbons (Gunter and Werner, 1997;Likholobov 2007) and different organic wastes (Long et al, 2007), (http://home.att.net/ ,africantech/GhIE/ActCarbon.PDF). The next step in the development of carbon adsorbents was stimulated by the First World War when respirators were created due to the necessity to neutralize chemical agents.…”

“…In contrast graphite carbons consist of free porous space which is a three-dimensional labyrinth of pores (Voyutsky, 1964;Drozdnik, 1997;Birdi, 2000;Pokonova, 2001;Mui et al, 2004;Malikov et al, 2007;Novoselova, 2008). This porous material has a structure which contains both ordered and disordered carbon rings.…”

“…There are a number of methods known for the modification of natural biopolymers to increase their hydrophobicity [7]. Since peat is composed of hydrophilic (water-soluble and easily hydrolysable) and hydrophobic (bitumen, waxes) components, its hydrophobisation can be carried out by using its own hydrophobic components condensing on the surface of material as a result of thermal treatment [3]. The chemical hydrophobisation of peat can be achieved using water-repellent agents of organic or inorganic origin, for example, sodium salts of fatty acids, organosilicon substances, solutions of Ca 2+ , Mg 2+ , Zn 2+ , Cu 2+ , Fe 2+ salts with carboxymethylcellulose additive and others [3].…”

The growing use and transport of crude oil and oil products has led to an increasing amount of spillages of various scales. In the event of an oil spill, it is important to stop the spill from spreading and to clean up the polluted environment. One of the possible ways of treating the polluted areas is the use of oil sorbents. The sorbents used for collecting oil in case of oil spills are mostly synthetic, which limits the possibilities of their disposal. The aim of our study is to investigate the possible use of peat and its modification products for oil and other hydrocarbon sorption. Peat is a prospective material for oil sorption because it has such advantages as low cost, biodegradability and relatively high parameters of specific surface area and porosity. At the same time, peat also has disadvantages, such as poor buoyancy characteristics, relatively low oil sorption capacity and low hydrophobicity. We have studied the sorption characteristics of native high-moor peat with different botanical compositions and levels of decomposition, as well as the effect of thermal treatment on the oil sorption capacity, buoyancy and water sorption capacity of peat in comparison with the effect achieved by means of two other methods of chemical modification: silylation and methylation. We have determined the optimal conditions for thermal modification of peat to have an effect on hydrocarbon sorption characteristics. Using the method of IR spectroscopy, we have investigated specific structural changes in peat, which resulted in the improvement of its sorptive characteristics.

Carbonization of peat under the action of microwave radiation was used to produce a microporous carbon material. The effect of the carbonization process parameters on the physicochemical, structural, and adsorption properties of the carbon material was examined. It was shown that the carbonization results in that the content of charged surface areas decreases due to the destruction of functional organic compounds, thee appears porosity, and the adsorption properties of the carbon material are improved.
