Abstract
Liquid bromine trifluoride and the solid complexes ClF 2 SbF 6 , BrF 2 SbF 6 , BrF 4 Sb 2 F 11 , IF 4 (SbF 6 ) 3 , and BrF 2 BiF 6 react spontaneously with radon and radon daughters at 25°C, converting the radioelements to nonvolatile ions and compounds. The reagents can be used in gas-scrubbing units to remove radon and radon daughters from air. The halogen fluoride-antimony pentafluoride complexes may be suitable for purifying air in uranium mines and analyzing radon in air, since they have low dissociation pressures at 25°C and are less hazardous to handle than liquid halogen fluorides.Keywords
