METHOD FOR PRODUCING GRANULATED ORGANOMINERAL SORBENTS Russian patent published in 1997 - IPC

Abstract RU 2081699 C1

FIELD: chemical industry, non-ferrous metallurgy. SUBSTANCE: proposed method comprises following process steps: mixing together sorbent powder with acetylcellulose solution in hydrophilic solvent prepared by redissolution by polymer coagulated by adding sodium carbonate solution to polymer solution; dispersion of slurry thus-prepared into weak mineral acid solution; washing resulting granules with water, followed by air drying. EFFECT: proposed method makes it possible to synthesize sorbents making departure from inorganic compounds of different classes. 1 tbl, 1 dwg
