Methods for theoretical prediction of deuterium recovery from the separation of water-isotope mixtures in a batch-type thermal diffusion column have been introduced. Theoretical predictions are found in fair agreement with the experimental results. Most of the predictions give higher values of separation than experiments. Predictions based on the constant and linear approximations for the pseudo product form of concentration are very similar and have better agreement with experiments than those based on the third type of approximation.
