Prediction of Gas Solubility in Molten Salts

The Solubilities of Hydrogen, Deuterium, and Helium in Molten Li2BeF4

“…Studies of the solubilities of gases in molten salts are sparse, and unresolved discrepancies between different investigators, as already pointed out by Paniccia and Zambón in (1972), are not uncommon. Moreover, it is not possible to resolve these discrepancies by appealing to theory, since an adequate theoretical treatment has yet to be developed (Lee and Johnson, 1969; Veleckis, et , 1971). In addition, it is not at all clear how some of the theoretical approaches that have been developed can be modified and extended to include molten salt mixtures.…”

Semi-empirical model for Henry’s law constant of noble gases in molten salts

“…An exponential relationship exists between Henry’s law constant and the Gibbs energy . Although is associated with surface energy 8 , 11 , this model was introduced to incorporate Gibbs volumetric energy. The enthalpy term of the method and our model remains constant at a given temperature.…”

“…An exponential relationship exists between Henry's law constant and the Gibbs energy G . Although G is associated with energy 8,11 , this model was introduced to incorporate Gibbs volumetric energy. The enthalpy term of the ln K e H method and our model The change in Gibbs free energy in 2LiF-BeF 2 system has been amended to include the appropriate correction for Henry's gas constant.…”

But in the real situation where the charge neutrality is held, the contribution from infinity can be neglected.)…”
