| 摘要 | In this paper, the solubility of unreported systems LiBr-NaBr-Li2SO4-Na2SO4-H2O, LiBr-KBr-Li2SO4- K2SO4-H2O and the subsystem LiBr-Li2SO4-H2O was measured by isothermal dissolution method at 298.15 K. Three phase diagrams are also given. It was found that the diagram of LiBr-Li2SO4-H2O system has only one invariant point of LiBr center dot 2H2O + Li2SO4 center dot H2O. The phase diagram of LiBr-NaBr-Li2SO4-Na2SO4- H2O system includes eight crystallization regions LiBr center dot 2H2O, Li2SO4 center dot H2O, NaBr center dot 2H2O, NaBr, Na2SO4 center dot 10H2O, Na2SO4, Li2SO4 center dot 3Na2SO4 center dot 12H2O, and Li2SO4 center dot Na2SO4. Five crystallization regions corresponded to two single salts KBr and K2SO4, two hydrate salts Li2SO4 center dot H2O and LiBr center dot 2H2O, and one double salt Li2SO4 center dot K2SO4 in LiBr-KBr-Li2SO4-K2SO4-H2O system. The relevant Pitzer parameter was obtained and the result predicted by Pitzer model was consistent with the experimental values. CO 2021 Elsevier Ltd. |
