METHOD OF PREPARING BIOSORBENT FOR RADIOACTIVE EUROPIUM AND AMERICIUM IONS Russian patent published in 1996 - IPC

Abstract SU 1827862 A1

FIELD: biotechnology. SUBSTANCE: producers of cellulolytic enzymes were used as microorganisms. Biosorbents were isolated by treatment of biomass with 0.25-1.50% spirituous solution of ortho-phosphoric acid at 10-15 C followed by washing solid phase with water excess to the neutral pH value. EFFECT: distribution coefficient of biosorbent is increased by 1.5 fold. 1 tbl
