FIELD: chemistry.
SUBSTANCE: absorbent material is made by treating lignin-cellulose material in the presence of a catalyst from a transition metal with oxidation. The oxidising agent is selected from a group consisting of hydrogen peroxide, hypochlorite, hypochloric acid or any combination thereof. The lignin-cellulose material is treated at pH from approximately 2 to approximately 6. The treated lignin-cellulose material has viscosity equal to or less than approximately 17 cP. The treated lignin-cellulose material is subjected to dry grinding. The dry ground lignin-cellulose treated material is used as an absorbent intermediate layer for making absorbents.
EFFECT: improved bacteria inhibition properties.
