Solubility Prediction of CsCl-Cs2SO4–H2O System at 298.15K Using the Ion-Interaction Model

摘要

The component solubilities of CsCl-Cs2SO4-H2O system at 298.15K were calculated by using Pitzer ion interactionmodel and its extended HW models. Excellent agreement with experimental solubilities indicated that the modelscan be successfully used to calculate the component solubilities. This study affords the necessary parameters for solubilitypredictions of complicated systems and establishes a theoretical basis for the separation of these valuable metals from saltlake brine.
