FIELD: chemistry.
SUBSTANCE: invention can be used in producing an adsorbent for efficient purification of water systems. The method of producing an adsorbent based on anatase-structured titanium dioxide using a kraft method involves mixing powdered titanium (IV) oxysulphate - sulphuric acid hydrate (TiOSO4·xH2SO4·yH2O) with water in weight ratio 1:(5.5-6.8), heating for 60 minutes without stirring at temperature 90-98°C, cooling and separating the residue by filtering. Further, the mixture is treated with a 0.1-0.4 M solution of an alkali metal hydroxide, washed with distilled water and acetone and dried in a drying chamber at temperature 90-95°C for one hour.
EFFECT: invention enables to obtain nanosized anatase-structured titanium dioxide with bismuth ion sorption capacity of 99%.
