摘要The present study deals with the estimation of deuterium recovery front the separation of water-isotope mixture (H2O-HDD-D2O) by continuous-flow thermal diffusion. First, the equations for predicting the degrees of separation for each component in H2O-HDO-D2O system were derived. The recovery of deuterium (D) was then estimated from the degrees of separation of HDO and D2O. The most important assumption in this work was that the concentrations of each component were at local equilibrium within the thermal diffusion column, i.e. H2O+D2O(The symbol is abbreviated)2HDO. It was found that D2O preferably transfers to the bottom end of the column, while HDO does the same for dilate feed concentration, but then transfers to the top of the column when the feed concentration of D2O, C(subscript 3F), increases to 0.3. The maximum total recovery of deuterium from HDO and D2O occurs at C(subscript 3F)=0.25.
