FIELD: chemistry.
SUBSTANCE: invention relates to production of silicate materials. Disclosed is a method of producing inverted-phase hydrophobisated polysilicate sorbents, which includes reaction of a hydrophilic silicate component with an amphiphilic silicate component in an aqueous medium. Co-condensation of said components is carried out with molar ratio of water to the sum of the silicate components of 124-250. An acidic and/or alkaline component is also added to the reaction mixture until polysilicate hydrogel forms. The obtained sorbent is intended for use as a filter medium and as an enterosorbent.
EFFECT: obtaining three-dimensional hydrogel of polysilicic acid containing hydrophilic and hydrophobic groups in an aqueous medium.
