Ion interaction approach to calculations of volumetric properties of aqueous multiple-solute electrolyte solutions

, , und . JOURNAL OF SOLUTION CHEMISTRY, 24 (10): 1025--1038 (1995)

Zusammenfassung

The ion interaction approach developed by Fitter wets used for the prediction of volumetric properties of mixed electrolyte solutions at 25 degrees C based on parameters calculated from experimental data for single-solute electrolyte solutions. Such an approach war shown to be especially effective for application to the calculation of volumetric properties of natural hypersaline brines and of industrial electrolyte solutions of large complexity. The use of the latest recommended sets of volumetric ion interaction parameters for single electrolyte solutions and symmetrical mixing parameters for Na-K-Cl ion combinations considerably improved the precision of the density calculations of highly concentrated mired electrolyte solutions and of various natural waters.
