Data Analysis for Electrolyte Systems : A Method Illustrated on Alkali Halides in Water

Abstract : In the recent years, the need to improve the thermodynamic models, particularly making them more precise and predictable for complex systems, has increased 1,2. The complexity of electrolyte systems is due to the strong interactions between ions, the hydration forces that take place during salt dissociation, and the physical forces at high concentrations of solute. Consequently, the existing thermodynamic electrolyte models show some limitations and are far from being completely optimized for industrial simulations. Thermodynamics based on electrolyte mixtures and mixed solvents requires further development and research 3. The EleTher Joint Industrial Project (JIP) aims at promoting research in this field. A practical workflow is under development where the first stage consists in analyzing the data.
