| titleOfInvention | Method of producing sorbent based on manganese dioxide for extracting lithium from solutions |
| abstract | The invention relates to chemical technology, in particular, to methods for obtaining sorbents for the extraction of lithium from solutions, can be used in the metallurgical, chemical and other industries of the industry, as well as in the treatment of industrial effluents and in analytical chemistry. The sorbent is obtained in the form of fiber by molding from a composition of the following composition by weight. %: modified manganese dioxide 4-24, fluoroplastic 8-12, polymer or oligomer of ethylene glycol 3.2-24, surfactant soluble in an organic solvent, 0.15-1.2, dimethylformamide or acetone to 100, in a precipitating bath containing 40-80% aqueous solution of an organic solvent. If ethylene glycol is used, polyethylene glycol mol. m. 5000-10000, dimethylformamide as an organic solvent, and molding is carried out in a precipitation bath containing 40-80% dimethylformamide. In the case of ethylene glycol oligomer, stearox 920 is used, acetone is used as an organic solvent, and molding is carried out in an organic bath containing 4-6% acetone. Then, the formed fibrous sorbent is additionally stretched by 300-700%. 1 hp ff, 3 tab. |
