METHOD OF PHOTOCHEMICAL SEPARATION OF MERCURY ISOTOPES Russian patent published in 1997 - IPC

FIELD: isotope separation. SUBSTANCE: mixture of mercury isotopes is irradiated in presence of oxygen and butadiene with mercury lamp light having wavelength corresponding to Hg-198 isotope emission to produce dump depleted in Hg-198 and Hg-201 isotopes and a mixture enriched with them. The latter is separated by the same technique with wavelength corresponding to Hg-196 isotope emission. The dump is irradiated with wavelength corresponding to emission of isotope Hg-196 and/or Hg-200 and/or Hg-202 to produce mixture of Hg-199 and 204 isotopes. This mixture is separated with wavelength correspond to Hg-196 isotope emission. Enrichment degree is 96.0-97.2% and output 1.32-1.62 mg/h. EFFECT: improved procedure. 3 cl, 4 dwg, 5 tbl
