FIELD: chemistry.SUBSTANCE: device for gas dispersion, applied for the supply of an industrial furnace gas, is placed on the bottom of a water-filled reaction tank. Husk of rice grains is loaded into bags and placed in the water-filled reaction tank. The husk of rice grains, loaded in the bags, is compacted into water. Then the industrial furnace gas is supplied into the tank through a device for gas dispersion. Water pressure in the water-filled reaction tank is applied to increase the solubility of carbon dioxide, contained in the industrial furnace gas. The obtained solution of carbonic acid reacts with metal ions in the husk of rice grains to form sediment. When the reaction finishes, the husk of rice grains is washed with salty water and squeezed to remove metal ions, which have attached to the husk of rice grains.EFFECT: method is economically effective, reduces the pollution of the environment and energy consumption and has the high efficiency factor.7 cl, 1 tbl, 3 dwg, 2 ex |
