Retarding Forces Cancellation in Electrolyte Solutions-An Electrical Approach

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...

Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

Wetting layers in electrolyte solutions

2014 When a predominantly nonpolar mixture is in contact with a chemically ionizable substrate, thick wetting layers of a predominantly polar phase can form on the substrate. This paper considers the effects of added salt on such layers. In the limit of low salt concentrations, the equilibrium thickness reduces to a result previously derived by the author. In the limit of high salt concentratio...

Electrolyte solutions at curved electrodes. II. Microscopic approach.

Density functional theory is used to describe electrolyte solutions in contact with electrodes of planar or spherical shape. For the electrolyte solutions, we consider the so-called civilized model, in which all species present are treated on equal footing. This allows us to discuss the features of the electric double layer in terms of the differential capacitance. The model provides insight in...

Experimental Investigation into the Transmembrane Electrical Potential of the Forward Osmosis Membrane Process in Electrolyte Solutions

The transmembrane electrical potential (TMEP) in a forward osmosis membrane process with a single electrolyte solution as the draw and feed solutions was investigated by experiments. The effects of membrane orientation, the electrolyte species (KCl, NaCl, MgCl2, and CaCl2), concentration and concentration ratio of solutions at both sides of membrane on water flux and TMEP were investigated. The...
