SYNTHESIS OF ORGANOMINERAL SORBENT BY MODIFYING DGK+GIPAN WITH KHOVDAK BENTONITE

Organomineral sorbents are prepared using inorganic and organic raw materials in different proportions. Enriched forms of bentonites are used for synthesis. For this, bentonite mineral samples were cleaned of water-soluble salts and sand by washing with distilled water. The enriched mass of bentonite was separated from the liquid by centrifugation, and then the bentonite was dried at 105ºC. Modification technology and cation exchange processes are as follows: enriched bentonite with a particle size of not less than 0.5 mm is filled with 0.1 M cation exchange solution in a ratio of 1:22 (volume) and stirred at 55°C for 2 hours. After this time, the bentonite is filtered and washed from Cl- (checked by adding AgNO3 solution), then placed in a drying cabinet and dried at 100-105ºC for 2 hours. NaCl solution was used as cation exchange solutions.
