METHOD OF PRODUCTION OF ORGANOMINERAL SORBENTS (VERSIONS) Russian patent published in 2002 - IPC

FIELD: production of organomineral sorbents. SUBSTANCE: proposed method consists in production of organomineral sorbents on base of zeolites through modification of base which was preliminarily heat-treated with natural high-molecular agents; used as high-molecular agents are polysaccharides-alginates or chitosan; modification of zeolites by above-mentioned polysaccharides is effected through their interaction under conditions of mechanic-chemical synthesis in reactor pf oscillating mill. Invention contains also description of production of zeolite-based organomineral sorbents through modification of base which was preliminarily heat-treated with natural high-molecular agents; used as high-molecular agents are polysaccharides-alginates or chitosan; modification of zeolites by above-mentioned polysaccharides is effected through their interaction in aqueous medium. EFFECT: possibility of producing sorbents for sorbing organic dyes of various nature; sorption of malachite green dye reaches 98% at its initial concentration of 6 mg/m. 10 cl, 2 tbl
