SOLID POLYMER SORBENT FOR ISOLATION OF FISSION MOLYBDENUM-99 FROM NEUTRON-IRRADIATED URANYL-SULFATE SOLUTION AND METHOD OF PREPARATION THEREOF

摘要

FIELD: nuclear power engineering. SUBSTANCE: sorbent has following structural formula: <EMI ID=0.2 HE=78 WI=87 TI=CHI> where R is styrene, acrylic acid ester, or vinyl acetate; X is <EMI ID=0.3 HE=12 WI=75 TI=CHI>. Sorbent is prepared by common condensation of maleic anhydride copolymer, bifunctional organic compound (hydroquinone, diethylene glycol, hexamethylenediamine, glycerol, etc.), and benzoin oxime in molar ratios 1:(0.25-5):(0.75- 0.5) at heating in polar solvent. EFFECT: improved selectivity and heat and radiation resistance. 4 cl, 1 dwg, 4 tbl
