FIELD: chemistry.
SUBSTANCE: invention relates to adsorption treatment of waste water. Disclosed is a method of reducing concentration of barium in water. The method includes preparing aqueous manganese oxide and mixing with barium-containing water. At pH higher than 4.8, aqueous manganese oxide acquires a negative charge and barium is adsorbed on the negatively charged surface. Manganese oxide with barium adsorbed on its surface is mixed with a flocculant. A treated output stream of water with low barium concentration is obtained after separating the formed sludge.
EFFECT: invention provides a simple technique of removing barium from waste water.
