Extension of the eSAFT-VR Mie equation of state from aqueous to non-aqueous electrolyte solutions

نویسندگان

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.

Extension of the Dense System Equation of State to Electrolyte Solutions

In this work we have applied the Dense System Equation of State (DSEOS) to electrolyte solutions. We have found that this equation of state can predict the density of electrolyte solutions very accurately. It has been tested for different electrolytes solutions at different temperatures and compositions. A hypothetical binary model has been applied to find the dependencies of parameters of ...

An Evaluation of Four Electrolyte Models for the Prediction of Thermodynamic Properties of Aqueous Electrolyte Solutions

In this work, the performance of four electrolyte models for prediction the osmotic and activity coefficients of different aqueous salt solutions at 298 K, atmospheric pressure and in a wide range of concentrations are evaluated. In two of these models, (electrolyte Non-Random Two-Liquid e-NRTL and Mean Spherical Approximation-Non-Random Two-Liquid MSA-NRTL), association between ions of opposit...
