Comparative study of electrolyte thermodynamic models for carbon dioxide solubility in water at high pressure

The electrolyte thermodynamic models have been extensively studied for carbon dioxide - water system for the prediction of vapour liquid equilibrium at low pressures. However, no guidelines are available for selection of electrolytic models which are applicable at high pressure for prediction of the...
