Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

The Surface Tension of Physiological Solutions

1. Data are given to show that surface tension values obtained by the ring method cannot be considered reliable when absolute values are desired. 2. Data are given to show that, in the case of solutions of semicolloids, surface tension values obtained for a definite period of time following the formation of a new interface cannot always be consistently reproduced by the ring method. 3. It is sh...

Prediction of Surface Tension in Single and Mixed Electrolyte Solutions

In this study, the Langmuir adsorption isotherm has been coupled with activity coefficient models for prediction of surface tension of single and mixed electrolyte solutions. Various activity models such as Meissner, Pitzer and extended UNIQUAC have been used and coupled with Langmuir adsorption isotherm. The model parameters were determined through mathematical optimization using experimental ...

Surface tension of ionic liquids and ionic liquid solutions.

Some of the most active scientific research fronts of the past decade are centered on ionic liquids. These fluids present characteristic surface behavior and distinctive trends of their surface tension versus temperature. One way to explore and understand their unique nature is to study their surface properties. This critical review analyses most of the surface tension data reported between 200...

Density, Viscosity and Surface Tension of Whey Protein Concentrate Solutions

We have determined the density, rheological behavior and surface tension of whey protein concentrate (WPC) solutions. Densities (r) were measured at concentrations of 0.05–0.40 w/w at temperatures of 20–35C. The results were expressed as a function of temperature and mass fraction (w). This function fit the data with deviations of less than 0.4%. Apparent viscosities (ha) for WPC solutions with...
