FIELD: chemistry.
SUBSTANCE: according to the method, ground biomass of hymenophores of fruiting bodies of timber fungi is treated with an aqueous solution of a surfactant and then boiled for 1 hour in a low-concentration alkali solution. After that the biomass is saturated with a 10% hydrogen peroxide solution. Repeated treatment with an alkali solution is then carried out, followed by washing with water, neutralisation with acid and treatment with acetone. Drying is carried out for 30 minutes in air.
EFFECT: obtaining powdered chitine-containing composites, characterised by higher sorption capacity.
