FIELD: chemistry.
SUBSTANCE: invention relates to sorption materials. Claimed is silica-containing sorption composition, which has formula: SiO2)x(OH)yMzSa, where M represents metal or metalloid cation, S represents sulphur-containing compound, selected from at least one of the following compounds: sulphides and polysulphides, where 0.01-100% of specific surface area are covered with functionalised organosilane. Molar ratio y/x constitutes from 0.01 to 0.5, molar ratio x/z constitutes from 3 to 300, and molar ratio a/z constitutes from 1 to 5.
EFFECT: obtained product has high parameters of specific surface and pore volume.
