FIELD: chemistry.
SUBSTANCE: Kamennoyarsky gaize of the Astrakhan region, containing (%) SiO2 - 86.2; Al2O3 - 4.15; Fe2O3 - 1.56; TiO2 - 0.2; K2O - 1.2; CaO - 1; Na2O to 0.5; MgO to 1, is taken as the raw material. The gaize is dried at a temperature of 100°C, crushed, sifted and fractions of different sizes are separated. Crushed gaize fraction recommended as a sorbent should contain 75% of particles with a size of 0.001 to 0.1 mm with residual humidity of 2-5%.
EFFECT: invention expands the spectrum of sorbents obtained from natural gaize.
