Аннотация: Porous materials from sapropels of lakes of the Novosibirsk Region of the organic (Lake Kachkulnya) and organomineral (Lake Barchin) types, as well as from solid residues of their thermal dissolution in ethanol were obtained by thermochemical activation methods with potassium hydroxide and one-step carbonization-activation by water vapour. Textural and adsorption properties of porous materials were studied. It was established that porous materials with the specific surface up to 618 m2/g, total volume of pores of 0.26 cm3/g (according to BET), sorption activity on iodine and methylene blue of 58.9 % and 189.1 mg/g, respectively, could be obtained by the thermochemical activation of sapropels of the organic type. It was shown that these materials could be used as organomineral sorbents in technologies of the sewage treatment from ions of heavy metals and air from vapours of low molecular mass hydrocarbons.
