PROBLEM TO BE SOLVED : To provide a method for concentrating oxygen isotopes which can concentrate 17O and 18O of stable oxygen isotopes in the state of oxygen and can be implemented by simple apparatus constitution and to provide an apparatus therefor.
SOLUTION : The method for concentrating the oxygen isotopes includes an ozone photolysis process in which ozone having a specified oxygen isotope in a molecule is decomposed selectively into oxygen by irradiating a mixed gas containing at least one rare gas selected from the rare gases of krypton, xenon, and radon and ozone with light and an oxygen isotope concentration process in which the oxygen obtained by decomposing ozone in the ozone photolysis process is separated from undecomposed ozone and the rare gas, and the oxygen isotopes are concentrated in the separated oxygen. |
