Solubility Modeling of Air in Aqueous Electrolyte Solutions with the e-CPA Equation of State

Accurate prediction of the solubilities of air (as well as nitrogen: N2; oxygen: O2; and argon) in aqueous electrolyte solutions is very important for geological studies and in the chemical industry. However, very few electrolyte equations of state have been successfully used for the calculations of these gas solubilities. This work presents a thermodynamic modeling study on the solubilities of N2, O2, argon, and gas mixtures in pure water and...
