METHOD OF PRODUCING LEAD HYDROXIDE Russian patent published in 1994 - IPC

FIELD: inorganic chemistry. SUBSTANCE: pulp of origin halenite in neutral 20-25% solution of sodium or potassium chloride is prepared. Said solution contains polyacrylamide, its quantity being 0.1-0.3 mg/l, mass ratio of solid and liquid phases being (2-4): 1. Then electrolysis is carried out by uninterrupted draining off upper layer of solution thus prepared hydroxide. The process takes place to isolate hydroxide and to remove mother solution for production fresh portions of pulp. EFFECT: increases desired product yield, decreases expense of its production. 1 tbl
