Abstract

Extraction characteristics of chloroform-water system were studied using lithium chloride and tetrafluoroborate as extracted salts and benzo-15-crown-5 as an extractant. Single-stage isotope separation factors (α) for lithium isotopes at different concentrations of lithium chloride in water were measured and multiplication of isotope effect was made by extraction chromatography. The magnitude of α for Li6-Li7 pair was 1.036 for chloride and 1.030 for tetrafluoroborate. Light lithium isotope is concentrated in organic phase. Extraction chromatography experiments were conducted in 1,1,7-trihydrododecafluoroheptanol-water extraction system for boron isotope separation using boric acid as extracted compound and trioctylamine as an extractant as well as in chloroform-water system with lithium tetrafluoroborate as extracted compound and benzo-15-crown-5 as an extractant. The upper assessment of α values for B10-B11 boron isotopes was found to be not larger than 1.005 for both systems.
