Thermodynamics of phase equilibria of aqueous (lithium sulfate + cesium sulfate), (sodium sulfate + cesium sulfate), and (potassium sulfate + cesium sulfate) at 298.15 K using Pitzer's model

Isopiestic Determination of the Osmotic and Activity Coefficients of Li2SO4(aq) at T=298.15 and 323.15 K, and Representation with an Extended Ion-Interaction (Pitzer) Model

“…[10,14,15], including the present results from Table 2 (excluding a few measurements as described above), are generally in good agreement. Osmotic coefficients from the isopiestic study of Majima et al [11,12] agree with the more consistent isopiestic results to within Δφ = ± 0.01 except at the two highest molalities where they are 0.015 to 0.03 lower; because of the low precision, these results were rejected.…”

“…There are several previous studies that reported isopiestic data for Li 2 [10][11][12]14,15] were recalculated for consistency using current critical evaluations of the thermodynamic properties of the reference standards NaCl(aq) [7], KCl(aq) [18], and H 2 SO 4 (aq) [19]. [10,14,15], including the present results from Table 2 (excluding a few measurements as described above), are generally in good agreement.…”

“…where R = 8.31451 J·K -1 ·mol -1 is the gas constant, T is the absolute temperature, and where: [10] and of Filippov et al [14,15], except for a few outliers as described in Tables 2 and 4.…”

“…The experiments of most of the series involved measurements at a single temperature, [10][11][12]14,15] were recalculated for consistency using current critical evaluations of the thermodynamic properties of the reference standards NaCl(aq) [7], KCl(aq) [18], and H 2 SO 4 (aq) [19]. [10,14,15], including the present results from Table 2 (excluding a few measurements as described above), are generally in good agreement.…”
