Abstract: A new thermodynamic model derived from a Helmholtz energy function is established by considering the contribution of various particle interactions in the electrolyte solutions to calculate the solubility of gases in aqueous electrolytes. A good agreement between the experimental data and calculation results is obtained. Meanwhile, the results show that this model is superior to the MPT EOS under elevated pressure.
