“…Badarayani et al modeled these data using the Young’s mixing rule, and they reported a standard deviation equal to 0.6261 for the density, versus the 0.0124 we obtained in this study. Our maximum absolute relative deviation was 1.52%.…”

“…To do this, the various ternary subsystems were studied using experimental data provided by the literature. Saluja et al measured the heat capacity of the Na–Ca–Cl, Na–Mg–Cl, and Ca–Mg–Cl ternary systems between T = (298.15 and 373.15) K. For density, the compilation of Laliberté and the data of Kumar, Zezin et al, , Qiblawey et al, , Deng et al, Yu et al , and Badarayani et al were used. First, the calculations were performed with PhreeSCALE using only the binary interaction parameters.…”

“…Their measurements were at temperatures between 288.15 and 318.15 K and for a higher ionic strength (8.3 and 9.6 mol·kg –1 ). Badarayani et al measured the density for the complex system at 298.15 K and for ionic strength of about 3 mol·kg –1 . In each case, the relative deviation, δ Y (eq ) and the standard deviation, σ (eq ) were computed.…”

This work is on in the volumetric and thermal properties of brines in the quinary Na−K−Ca−Mg−Cl−H 2 O chemical system. Its objective is twofold. First, by acquiring original data for temperatures ranging from 278.15 to 353.15 K and ionic strengths ranging from 1.3 to 5.1 mol•kg −1 it aimed to add to the experimental data set, usually acquired only at high ionic strengths or at 298.15 K. Experimental solution density was measured using a vibrating-tube densitometer with relative uncertainty, Δρ/ρ, better than 6 × 10 −6 . This property, combined with volumetric heat capacity measurements, provided the isobaric heat capacity of solution determined with a mean relative deviation better than 0.3%. Second, we used PhreeSCALE software to compute the density and heat capacity of the chemical system of interest, simultaneously applying the Pitzer and the Helgeson−Kirkham−Flowers (HKF) equations. We propose a new set of specific interaction parameters so that published and newly measured experimental data can be described accurately. We show that only binary interaction parameters are necessary and that ternary interaction parameters could be set to zero.

SAFT2 with individual-ion parameters, referred to as ion-based SAFT2, is used to represent the properties of aqueous electrolyte solutions. A new set of parameters for 5 cations (Li+, Na+, K+, Ca2+, and Mg2+) and 6 anions (Cl-, Br-, I-, NO3 -, SO4 2-,and HCO3 -) is obtained from the fitting of the experimental mean ionic activity coefficients and liquid densities of 24 aqueous single-salt solutions at 298.15 K. The ion parameters are universal and transferable to different salts containing the same ion. Because of the peculiar segment energy of K+, a mixing rule with a binary interaction parameter for the segment energy describing the short-range interactions between K+ and other cations is needed. The binary interaction parameter is derived from the osmotic coefficients of chloride solutions. The predictions of the osmotic coefficients, vapor pressures, and liquid densities of single- and multiple-salt solutions including seawater (brine) are found to agree with experimental data.
