<p>The object of the present invention is to provide an oxygen isotope concentration method capable of concentrating the stable oxygen isotopes of 17 O and 18 O which can be carried out using a simple device configuration. An oxygen isotope may be concentrated in a dissociation reaction product by irradiating a gas containing a peroxide selected from hydroperoxides, (di)alkyl peroxides, peroxyacids including peracids, (di)acyl peroxides, peroxy esters, peroxycarbonates, peroxydicarbonates, diperoxycarbonates, peroxalates, cyclic peroxides, ozonides and endoperoxides, nitrite esters and nitrate esters, and selectively dissociating a peroxide containing a specific oxygen isotope in its molecule.</p> |
