PROCESS FOR PREPARING SOLID BIOSORBENTS FOR RECOVERY OF METALS Russian patent published in 1995 - IPC

Abstract RU 2045574 C1

FIELD: biotechnology, in electroplating processes and in treatment of non-ferrous metals. SUBSTANCE: a microbial biomass is immobilized to a polymer carrier, the immobilization being conducted during copolymerization of mono-and/or divinyl aromatic or acrylic compounds in the presence of an organic solvent at a biomass to monomers to solvent weight ratio of 0.4-0.6: 0.6-0.4: 0.5-1.0 in the presence of a radical initiator at 80-90 C for 8 to 10 hours. The microbial biomass includes brewers or nutrient yeast or ASPERGILLUS TERREUS BKM F 2220. EFFECT: more efficiency preparation process. 3 cl, 1 tbl
