A Determination of the Equilibrium Constant of HTO-H_2S Reaction

The equilibrium constants of the chemical exchange reaction between HTO and H_2S are determined at 1 atm to enrich tritiated water. The separation factor of one stage is defined, and it is increasing with the increase of temperature in the batch method. For the first step to make a practical application of the chemical exchange reaction to enrich tritium, the H_2S gas circulation method is investigated
