چکیده
In this work, the eSAFT-VR Mie equation of state (EoS) is extended to low relative permittivity, non-aqueous solutions. The effect using different permittivity relations for electrolyte solutions studied, ranging from experimentally measured values a salt-composition independent permittivity. Furthermore, approaches characteristic diameters in Debye-Hückel and Born terms presented. EoS reparametrized aqueous mean ionic activity coefficients, individual ion coefficients densities with Afterwards, performance these models on evaluated based Mean Ionic Activity Coefficients salts conclusion that mole fraction mixing rule yields best extrapolation solutions, achieves quantitative predictions monovalent methanol ethanol without additional adjustable parameters.
