Abstract
SOLVENT extraction of xenon has never been reported. Two years ago, one of us (R. K.) noticed that cæsium-138 (half-life 32.2 min) was extracted in di-isobutylketon (DIBK) when he was carrying out a rapid solvent extraction separation of short-lived selenium activities from uranium fission products1. The caesium-138 activity did not appear in the DIBK phase, if the hydrobromic acid solution of uranium fission products was heated or air-bubbled prior to the extraction of selenium activities into the organic solvent. This phenomenon suggests to us that xenon-138 (half-life 17 min) is extracted into the DIBK phase.
