The distribution of hydrogen isotopes between azeotropic mixtures of strong acids with water and the vapor existing in equilibrium with the mixture is definable with chemical exchange equilibria. An expression for the total separation factor alpha = (D/H)/sub vap//(D/H)/sub liq/ is given and evaluated fo r strong monobasic acids. If such a mixture is subjected to counter-current distillation, deuterium enrichment occurs at the head of the column. For the azeotropic mixture HNO/sub 3//H/sub 2/O alpha = 1.059 at 121 deg C. It would be expected that at reduced pressures the separation factor would attain higher values. (J.S.R.)
