MSA-NRTL model for the description of the thermodynamic properties of electrolyte solutions

Abstract

The mean spherical approxn. (MSA) approach for electrolyte solns. is combined with a modified non-random two-liq. (NRTL) approach. The resulting model is suitable for a description of the thermodn. properties of electrolyte-multisolvent systems. The ability of this MSA-NRTL model is investigated by examg. activity and osmotic coeffs. of binary and ternary electrolyte solns. Esp. for non-aq. solns., the model is superior to std. semi-empirical calcns. used in the chem. industry.
