An Equation of State for Nonaqueous Electrolyte Solutions
A two parameters equation of state (EOS) for nonaqueous electrolyte solutions system has been developed. The equation is in terms of Helmholtz free energy and incorporated with results of low density expansion of non-primitive mean spherical approximation. The EOS was tested for experimental data reported in literatures of 9 nonaqueous single electrolyte solutions of which the temperature was 2...
متن کاملAn 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...
متن کاملDielectric Properties of Polyelectrolyte Solutions
Dielectric properties of polyelectrolyte solutions have been studied experi mentally for more than thirty years, but progress in understanding these properties has been rather slow. A particularly unfavorable combination of experimental difficulties and unsettled theoretical problems has noticeably influenced both the extent of the work devoted to this subject and the pace in which explanation...
متن کاملDielectric relaxation of electrolyte solutions using terahertz transmission spectroscopy
We use terahertz ~THz! transmission spectroscopy to obtain the frequency dependent complex dielectric constants of water, methanol, and propylene carbonate, and solutions of lithium salts in these solvents. The behavior of the pure solvents is modeled with either two ~water! or three ~methanol and propylene carbonate! Debye relaxations. We discuss the effects of ionic solvation on the relaxatio...
متن کاملUnravelling the anomalous dielectric permittivity of nanoconfined electrolyte solutions.
The dielectric properties of sodium chloride solutions confined in a hydrophilic nanocavity were investigated by means of molecular dynamics simulations. Unlike what is observed in the bulk phase, three dielectric regimes were evidenced, namely an anomalous increase in the dielectric permittivity at low concentrations (with respect to confined pure water), a dielectric plateau at intermediate c...
