Abstract
FIELD: inorganic chemistry, methods to produce sorbents, that are used in hydraulic metallurgy of non-ferrous and rare-earth metals and for purification of corresponding works industrial waters in particular, that is for production of oxyhydrate sorbents. SUBSTANCE: method to produce sorbent, that has metal oxyhydrate, provides for its settling in the form of hydrogel using interaction of metal salt with alkaline in presence of organic substance, its holding and filtering with following drying and granulating of ready-made product. Water soluble trivalent iron salt reacts with alkaline. Reaction between initial substances is carried out in low concentration alkaline solution. Then bichromate of potassium is added. Bichromate of potassium is taken in molar ratio to iron equal to (0.1 - 0.125) : 1. As organic substance nitryltrimethylphosphonic acid is used with molar ratio to iron equal to (0.01 - 0.07) : 1. After addition of nitryltrimethylphosphonic acid value of pH is raised to 3.5 - 4.5 with following washing potassium bichromate out using ammonia solution. EFFECT: improved process. 1 tbl
