FIELD: chemistry.
SUBSTANCE: invention relates to sorbents for purification of water from arsenic. A sorbent contains substances, selected from polyvinyl alcohol, polyacrylamide, methycellulose, polyethylene glycol as a water-soluble polymer. A method of the sorbent obtaining includes mixing wastes of deironing plants, containing 10-12% of iron oxyhydroxide with a water solution of a polymer and glycerol. A mixture is processed by ultrasound, kept for 24 hours. The formed sediment is dried at 50-60°C.
EFFECT: obtaining the sorbent for purification of water media from arsenic contains nanophase oxyhydroxide, separated from the wastes of plants for underground water deironing, the water-soluble polymer and glycerol.
