The purification of 18O-water [PDF]
Australian Journal of Chemistry, 1959 A reliable method for the purification of 15 to 20 mg samples of 18O-water, as a preliminary step to the measurement of isotopic composition by a density technique, is described. The method is based on the use of copper oxide as the oxidizing agent but negligible isotopic dilution is involved as the oxygen of the oxide is obtained by electrolysing a ...
