AB  - This study present estimation of the thermodynamic parameters and the influence of ionic activity coefficient on the thermodynamic equilibrium constant of adsorption of phosphates on fly ash. The adsorption was conducted over a wide range of initial phosphate concentrations at different pH values pH = (3; 7; 10). The adsorption results were treated using the Langmuir, Freundlich and Sips adsorption isotherms, which provide information about the maximum adsorption capacity. The Langmuir and Sips isotherms were a satisfactory fit to the adsorption data, especially at pH = 3, with an acceptable regression coefficient over the entire concentration range, Langmuir (r2 = 0.9737) and Sips (r2 = 0.9969). The estimated maximum phosphate sorption capacity of fly ash was 6.21 ± 0.68 (mmol·g−1) according to Langmuir and 4.19 ± 0.16 (mmol·g−1) according to the Sips model, at pH = 3.0. However, there is no data in the published literature for estimating the thermodynamic parameters of the phosphate adsorption process using thermodynamic models for activity coefficients. Novel approach of this paper was determination of the thermodynamic equilibrium constant and Gibbs free energy, using the Pitzer ion-interaction model to predict the nature of adsorption. The Pitzer-ion interaction model was used for the mixed ionic systems, taking into consideration the effect of other present ions besides phosphates in the equilibrium solution resulting from fly ash desorption. The procedure for comprehensive estimation of the ion activity coefficient at maximum adsorption capacity and the dimensionless thermodynamic equilibrium constant using Langmuir's and Sips's constants was presented. The calculated value of the phosphate activity coefficient in the equilibrium solution was γH = 0.7003 ± 0.0027 and the converted molar activity coefficient was γH = 0.6903 ± 0.0027. The estimated values of Gibbs free energy were: ΔGL = −6.788 ± 0.521 kJ·mol−1 based on Langmuir equilibrium constant and ΔGa = −7.707 ± 0.527 kJ·mol−1 based on activity and thermodynamic equilibrium constant. According to Sips model, the adsorption process is even more spontaneous, with the Gibbs free energy calculated using the phosphate activity coefficient and the thermodynamic equilibrium constant, ΔGa = −9.707 ± 0.617 kJ·mol−1. Consideration of the ionic activity coefficient is particularly important for large, charged adsorbates at higher concentrations, as the absolute difference in free energy for adsorption is app. 12 %. The scientific contribution is reflected in obtaining the necessary and more accurate information for the improvement of adsorption processes and possibly for the upgrading of fly ash in overall wastewater treatment technology.

AB  - The mean ionic activity coefficients of NaCl in a ternary system {yNaCl + (1 – y)Na2HPO4}(aq) were determined from measurements of the electromotive force (EMF) where the NaCl ionic strength fraction was y = (0.3012; 0.4015; 0.5011; 0.5988; 0.7706; 0.8997) in the range of total ionic strength of the solution Im = 0.0701–1.0161 mol kg–1 at temperature T = 298.15 K. A cell of the Na–ISE| (Formula presented.) |AgCl|Ag, type was employed for the EMF measurements. The experimental results from this work and the model of Pitzer’s were used to determine the mixing parameters. Good agreement was found between the experimental and calculated values of the mean ionic activity coefficients of NaCl with a standard deviation of fit 1.5 × 10–3. The values of the osmotic coefficients of the system {yNaCl + (1 – y)Na2HPO4}(aq) were estimated on the basis of the determined parameters and compared with literature data. The differences in the osmotic coefficients between the estimated and experimental values were negligible.

AB  - Due to the similar chemical properties of Ni2+ and Co2+, several dozens of adsorptive stripping voltammetric (AdSV) methods have been developed for their simultaneous determination. The question was would there be some benefits if a stripping method made for simultaneous determination of Ni2+ and Co2+ will be optimized for the determination of only one of them (Ni2+). It was found that the optimized method has for an order of magnitude lower LOQ (1.89×10−10 M), an order of magnitude lower influence of Co2+, and the applicability of one calibration line for four orders of magnitude of Ni2+ concentration. The influence of some common anions and cations has been examined. The developed method was successfully applied for nickel content determination in real samples. The suitability of the developed method for the determination of Co2+ from the same solution in the second run, upon optimizations of deposition potential and time, was also explored. The LOQ obtained for Co2+ (3.61×10−11 M) is almost two orders of magnitude lower than LOQ of the method for simultaneous determination of both cations and, its LOD and LOQ are among few lowest obtained by AdSV methods for Co2+ determination. The developed method for Ni2+ and Co2+ determination from the same solution in two successive runs has significantly better analytical performances than the starting method for their simultaneous determination in one run.

AB  - The mean activity coefficients of KCl in the ternary system {y KCl + (1 – y) K2HPO4}(aq) were experimentally determined at T = (298.15 ± 0.01) K by the electromotive force measurement (EMF method) using the cell of the type, K–ISE∣KCl(mKCl), K2HPO4(mK)∣Ag∣AgCl (ISE = ion-selective electrode), in the range of total ionic strength of the solution Im = (0.10 to 1.00) mol·kg−1 at different ionic strength fractions of KCl being y = (0.1011; 0.1997; 0.3016; 0.4027; 0.5006; 0.6018; 0.7018; 0.8051; 0.8988; 1). In addition, the osmotic coefficients of the system have been measured at the same temperature by the isopiestic vapor pressure method over the range of ionic strengths from (0.96698 to 2.21602) mol⋅kg−1 using KCl(aq) as the reference solution, at ionic strength fractions of KCl being y = (0.2063; 0.3849; 0.6099; 0.8011; 1). Values of the mean ionic activity coefficients of KCl and osmotic coefficients in the system {yKCl+(1–y)K2HPO4}(aq) were treated by an extended form of Pitzer's ion-interaction model, Scatchard's neutral-electrolyte model and Clegg–Pitzer–Brimblecombe's equations based on the mole-fraction-composition scale. All three models gave similar quality representations of both sets of experimental results. There are two sets of previously published isopiestic data that were taken into consideration during treatment. The model parameters were fitted and optimized to all available thermodynamic data from EMF and isopiestic measurements to obtain an accurate and self-consistent description of properties and to form a set of parameters that can be used in a wide range of ionic strength of the system. The standard deviation of the fit for the ionic strength range from Im = (0.0897 to 10.4350) mol·kg−1 with two optimized mixing parameters of Pitzer's model without higher–order electrostatic terms was for the mean ionic activity coefficients of KCl and osmotic coefficients, s.d.

In order to generate a set of parameters that can be applied in a wide range of mixed solution ionic strengths, the Pitzer, Scatchard, and Clegg-Pitzer-Brimblecombe models were used to fit all available experimental data, including cell potential and isopiestic measurements from the literature. The experimental and calculated values of thermodynamic properties for the studied system are in excellent agreement. Potential interactions and solution structure were discussed by means of the excess free energy of mixing via potential pairs, triplets, or quads for the investigated solution using the Scatchard model mixing parameters.

AB  - Isopiestic measurements have been made at 55 compositions of the {yK(2)HPO(4) + (1 - y)KH2PO4}(aq) system at T = (298.15 +/- 0.01) K, 11 for each of the limiting binary solutions and 33 for mixture compositions at K2HPO4 stoichiometric ionic strength fractions y = (0.23330, 0.47671, and 0.73177), using KCl(aq) as the reference standard. Model parameters for the binary subsystems were evaluated at this temperature for an extended form of Pitzer's ion-interaction model and also for the Clegg, Pitzer and Brimblecombe model based on the mole-fraction-composition scale, using the present isopiestic results along with critically-assessed osmotic coefficients for both of these aqueous electrolytes as extracted from the published literature. The thermodynamic models for KH2PO4(aq) extend to slightly above the saturated solution molality at T = (298.15 +/- 0.01) K, whereas those for K2HPO4(aq) extend to m = 9.7429 mol.kg(-1), which is the molality of the saturated solution, also at T = (298.15 +/- 0.01) K. These results yield the CODATA-compatible standard Gibbs energy of formation Delta(f)G(m)(o)(K2HPO4 center dot 3H(2)O; cr; 298.15 K) = -(2367.70 +/- 1.60) kJ.mol(-1). The 33 osmotic coefficients for the ternary mixtures were likewise represented with these models, using both the usual Pitzer mixing terms and also Scatchard's neutral-electrolyte model mixing terms for the extended ion-interaction model. Two mixing parameters are needed for each of the three models for {yK(2)HPO(4) + (1 - y)KH2PO4}(aq), and both of these ion-interaction models give similar high-quality representations of the experimental results. However, the Clegg, Pitzer and Brimblecombe model had more difficulty in representing the osmotic coefficients of K2HPO4(aq), especially below 3 mol.kg(-1), and consequently the corresponding mixture model with two mixing parameters is slightly less accurate for representing the osmotic coefficients. The maximum difference in calculated values of the mean molality-based activity coefficients for the two recommended extended Pitzer models with the different types of mixing terms are 0.0061 for the trace activity coefficient of K2HPO4(aq) in KH2PO4(aq) but with much better agreement at most mixture compositions.

AB  - Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4and Na2HPO4at T = 298.15 ± 0.01 K, at NaH2PO4ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and 1), where the ionic strength fractions were calculated by assuming complete electrolytic dissociation of NaH2PO4as 1:1 and Na2HPO4as 2:1 electrolytes; CaCl2(aq) was used as the reference standard solution. Model parameters for an extended form of Pitzer's ion-interaction model and also for the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale were evaluated at T = 298.15 K for both NaH2PO4(aq) and Na2HPO4(aq) using the isopiestic results from this study (17 values each) together with numerous critically assessed osmotic coefficients for both electrolytes taken from the published literature. The thermodynamic models for NaH2PO4(aq) extend to m = 7.5 mol·kg-1, whereas those for Na2HPO4(aq) extend to m = 2.6050 mol·kg-1, which is well above the solubility limit for the thermodynamically stable phase Na2HPO4·12H2O(cr). The 51 osmotic coefficients for the ternary mixtures were treated with these two models together with Scatchard's neutral-electrolyte model; one previous set of osmotic coefficient values for {yNaH2PO4+ (1 - y)Na2HPO4}(aq) mixtures was found in the literature [ Scharge, T.; et al.

AB  - Isopiestic measurements have been made for aqueous solutions of the common sodium cation mixtures of NaH2PO4 and Na2HPO4 at T = 298.15 +/- 0.01 K, at NaH2PO4 ionic strength fractions y = (0, 0.24851, 0.49862, 0.74544, and 1), where the ionic strength fractions were calculated by assuming complete electrolytic dissociation of NaH2PO4 as 1:1 and Na2HPO4 as 2:1 electrolytes; CaCl2(aq) was used as the reference standard solution. Model parameters for an extended form of Pitzer's ion-interaction model and also for the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale were evaluated at T = 298.15 K for both NaH2PO4(aq) and Na2HPO4(aq) using the isopiestic results from this study (17 values each) together with numerous critically assessed osmotic coefficients for both electrolytes taken from the published literature. The thermodynamic models for NaH2PO4(aq) extend to m = 7.5 mol.kg(-1), whereas those for Na2HPO4(aq) extend to m = 2.6050 mol.kg(-1), which is well above the solubility limit for the thermodynamically stable phase Na2HPO4 center dot 12H(2)O(cr). The 51 osmotic coefficients for the ternary mixtures were treated with these two models together with Scatchard's neutral-electrolyte model; one previous set of osmotic coefficient values for {yNaH(2)PO(4) + (1 - y)Na2HPO4}(aq) mixtures was found in the literature [Scharge, T.; et al. J. Chem. Thermodyn. 2015, 80, 172-183], and hence an analysis and comparison were made of our results with theirs.

AB  - Isopiestic measurements have been made for aqueous mixtures of NaH2PO4 and KH2PO4 at T=(298.15 +/- 0.01) K, at NaH2PO4 ionic strength fractions y=(0, 0.19108, 0.38306, 0.58192, and 1), assuming that both electrolytes dissociate as 1:1 electrolytes, using KCl(aq) as the reference standard solution. Model parameters for an extended form of Pitzer's ion-interaction model and also for the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale were evaluated at T=298.15K for NaH2PO4(aq) using the present isopiestic results (13 values), as were those for KH2PO4(aq) using the present isopiestic results (12 values), together with numerous critically-assessed osmotic coefficients for both electrolytes taken from the published literature. The thermodynamic models for KH2PO4(aq) extend to m=2.187molkg(-1), which is slightly above saturation, while those for NaH2PO4(aq) extend to m=7.5molkg(-1), which is below saturation. The 39 osmotic coefficients for the ternary mixtures from the present study along with 42 values from a published study were likewise represented with these models, with both the usual Pitzer mixing terms and also Scatchard's neutral-electrolyte model mixing terms being used for the extended ion-interaction model. Two mixing parameters were needed for each of the models, and all three models gave similar quality representations of the experimental results. Maximum differences in calculated values of mean molality-based activity coefficients for these three models are (+/-)(NaH2PO4)0.0080 and (+/-)(KH2PO4)0.0043. The experimental results were also found to nearly conform to Zdanovskii's rule.

AB  - A new Bi-rich part of Bi2O3-PbO phase diagram was determined using differential thermal analysis and X-ray powder diffraction techniques. Four solid solutions, alpha-Bi2O3, gamma-Bi2O3, d-Bi2O3 and ss(ss)-Bi8Pb5O17, can be distinguished below 37.5 mol % of PbO and one compound, ss(2)-Bi8Pb5O17. Two of them, d-Bi2O3 and ss(ss)-Bi8Pb5O17 are high-temperature phases. The large field of gamma-Bi2O3 stability was implemented making the crucial difference comparing to phase diagrams from the Bi2O3-PbO system published so far.

AB  - Isopiestic (vapor pressure) measurements were made for aqueous mixtures of Mg(NO3)(2) and MgSO4 at T = (298.15 +/- 0.01) K with Mg(NO3)(2) ionic strength fractions y = (0.19691, 0.42542, 0.60113, 0.79583, and 1), along with a separate series of measurements for MgSO4(aq), y = 0, all using KCl(aq) as the reference standard. The resulting 44 molality-based osmotic coefficients for the ternary mixtures, ionic strength range I-m = (2.5924-8.4583) mol-kg(-1), were modeled with an extended form of Pitzer's ion interaction model, both with the usual Pitzer mixing terms and also with Scatchard's neutral electrolyte model mixing terms, and also with the Clegg-Pitzer-Brimblecombe model based on the mole-fraction-composition scale. The molality-based osmotic coefficients phi of these mixtures at each fixed ionic strength fraction fall in a regular order between those of the corresponding limiting binary solutions with no crossovers in this ionic strength range. Model parameters for Mg(NO3)(2)(aq) and MgSO4(aq) at T = 298.15 K needed for these calculations were evaluated by using the present isopiestic results along with other sets of reliable osmotic coefficients gleaned from the published literature. Our osmotic coefficients for the ternary system are compared with those from a previous isopiestic study and a hygrometric study and the present results were judged to be more accurate. For this ternary system, both mixing parameters are needed for the extended Pitzer model with Pitzer mixing terms {standard uncertainty of fit u(phi)= 7.0 x 10(-3)} whereas three parameters gave a significantly better fit when the Scatchard mixing terms are used {standard uncertainty of fit u(phi) = 4.0 x 10(-3); the fits with two Scatchard mixing parameters did slightly better than the fit with both Pitzer mixing terms}, as did the Clegg-Pitzer-Brimblecombe model with three mixing parameters {standard uncertainty of fit u(phi) = 5.9 x 10(-3)}, with use of the three Scatchard mixing parameters giving the most precise representation of the experimental results. Including higher-order electrostatic mixing terms did not improve the representations but had the opposite effect.

AB  - Isopiestic measurements have been made for aqueous mixtures of Na2HPO4 and K2HPO4 at T = (298.15 +/- 0.01) K, at Na2HPO4 ionic strength fractions y = (0.2023, 0.4060, 0.6027, 0.8007, and 1), using KCl(aq) as the reference standard solution. The resulting 48 molality-based osmotic coefficients for the ternary mixtures were modeled with an extended form of Pitzer's ion-interaction model, with the usual Pitzer mixing terms and also with Scatchard's neutral-electrolyte model mixing terms, along with the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale. There are no previously published isopiestic measurements for this ternary system. Model parameters for Na2HPO4(aq) at T = 298.15 K were also evaluated using the present isopiestic results (12 values) along with three other sets of osmotic coefficients from isopiestic measurements taken from the published literature, and all four sets of osmotic coefficients are in good agreement; model parameters for K2HPO4(aq) are already available from our earlier work: (PopoviAc et al. in J Solution Chem 40:907-920, 2011). For this ternary system, only one mixing parameter is needed for each of the three models because the ionic strength dependences of the osmotic coefficients of Na2HPO4(aq) and K2HPO4(aq) are very similar, as expected from their very similar chemistry, with the two variants of the extended Pitzer model giving slightly better representations of the experimental results than the Clegg-Pitzer-Brimblecombe model. Maximum differences in calculated values of mean molality-based activity coefficients for these three models are a dagger gamma (+/-)(Na2HPO4) aecurrency sign0.004 and a dagger gamma (+/-)(K2HPO4) aecurrency sign0.008 for ionic strengths I (m) aecurrency sign 2.0 mol center dot kg(-1), with the largest differences occurring for the trace and near-trace activity coefficients of one solute in a solution of the other solute at higher ionic strengths and solutions rich in K2HPO4 at intermediate ionic strengths. These new results complement our earlier investigations of aqueous common-cation mixtures of K2HPO4 with KCl, KBr, KNO3 and K2SO4.

Maximum differences in calculated values of mean molality-based activity coefficients for these three models are a dagger gamma (+/-)(Na2HPO4) aecurrency sign0.004 and a dagger gamma (+/-)(K2HPO4) aecurrency sign0.008 for ionic strengths I (m) aecurrency sign 2.0 mol center dot kg(-1), with the largest differences occurring for the trace and near-trace activity coefficients of one solute in a solution of the other solute at higher ionic strengths and solutions rich in K2HPO4 at intermediate ionic strengths. These new results complement our earlier investigations of aqueous common-cation mixtures of K2HPO4 with KCl, KBr, KNO3 and K2SO4.",

AB  - Experimental results on isopiestic measurements for three ternary aqueous solutions of K2HPO4 with KCl, KBr, and KNO3 at T = 298.15 K were modeled with the Clegg-Pitzer-Brimblecombe equation based on mole-fraction-composition scale yielding appropriate mixing parameters, for the estimation of thermodynamic activities of solute components. The results for mean ionic activity coefficients of electrolytes in ternary solutions, calculated this way, are showing specific behavior depending on total ionic strength and ionic strength fractions of electrolytes. The activity coefficients of KCl in {yKCl + (1-y)K2HPO4}(aq) and of KBr in {yKBr + (1-y)K2HPO4}(aq) are changing consistently from the ionic strength and their ionic strength fractions contrary to activity coefficients of KNO3 in {yKNO(3) + (1-y)K2HPO4}(aq). In addition, molality of K2HPO4 aqueous saturated solution, in equilibrium with K2HPO4 center dot 3H(2)O(cr), and appropriate osmotic coefficient at T = 298.15 K, were determined by the isopiestic method.

AB  - The molality-based osmotic coefficients of aqueous mixtures of K2SO4 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method, at K2SO4 ionic strength fractions y = (0.21008, 0.39887, 0.60657, 0.80517, and 1) over the ionic strength range (1.3167 to 1.9587) mol . kg(-1), using KCl(aq) as the reference standard solution.

AB  - The photocatalytic efficiency of a recently synthesized TiO2 powder, denoted P160, for the degradation of the Dye C.I. Reactive Orange 16 in natural and artificial seawater was investigated in comparison to its efficiency in deionized water and the efficiency of a standard TiO2 powder, Degusa P25. It was shown that the photocatalytic efficiency of P160 was slightly higher than that of P25, probably due to slightly higher specific surface area, higher pore volume and larger pores of the powder P160. The efficiency of both photocatalysts in natural and artificial seawater was significantly lower than in deionized water. The overall rate of dye degradation for both types of photocatalysts was slightly higher in artificial seawater than in natural seawater, which shows the influence of organic compounds naturally present in seawater on the photocatalysts activity. A saturation Langmuir-type relationship between the initial degradation rate and the initial dye concentration indicated that adsorption plays a role in the photocatalytic reaction. The photodegradation rate constant, k, which represents the maximum reaction rate, had similar values for P25 and P160 in all types of water due to the similar properties of the photocatalysts.

AB  - In this study, in situ Al-27 NMR spectroscopy was used to gain detailed information concerning kinetics of zeolite A crystallization. Changes of relative intensity and width at half-height of NMR lines at 59 ppm ascribed to Al(OSi)(4) solid structures units and at 79 ppm to Al(OH) T ions in liquid phase during crystallization, were observed. Normalized curves for series of synthesis, performed under different batch molar composition, were used for kinetic analysis applying Sharp and Hancock approach. The influence of total batch Na2O concentration (H2O/Na20 was 20 and 32) for three specific batch SiO2/Al2O3 molar ratios (1.7, 2.0 and 2.5) on the kinetic parameters was investigated. Kinetic analysis of line at 79 ppm provided values of parameter n that ranged from 0.93 to 1.97 indicating contribution of both diffusion and phase boundary controlled mechanisms, depending on batch SiO2/Al2O3 molar composition. On the other hand, analysis of line at 59 ppm showed strong correlation to Na2O batch content. Values of n from 1.94 to 3.34 for syntheses performed at lower alkalinity conditions (H2O/Na2O = 32) indicate Avrami-Erofe'ev nucleation and crystal growth model. Almost dominant presence of diffusion mechanism for synthesis conducted at higher alkalinity conditions (H2O/Na2O = 20) was verified by obtained values of n gathered around 1.5.

AB  - In the salt solubility predictions for K+-Na+-Mg (4) (2-) aqueous solution the treatment of thermodynamic data of three-component systems at T = 298.15 K involved the application of the Extended Pitzer's ion-interaction model for the pure and mixed electrolyte solutions and criteria of phase equilibrium. Osmotic coefficients data of three-component systems were revised according to recently published parameters of the solutions NaCl(aq) and KCl(aq) that served as reference standards in isopiestic measurements. Parameters of the extended ion-interaction model of K2SO4(aq) are determined by treatment of experimental and predicted values of osmotic coefficient in supersaturated region obtained by the Zdanovskii-Stokes-Robinson rule. Results of salt solubility prediction were compared to experimental solubility data from literature. The agreement between calculated and experimental solubility data in the systems K2SO4 + MgSO4 + H2O, Na2SO4 + MgSO4 + H2O, and Na2SO4 + K2SO4 + H2O at T = 298.15 K, was excellent.

AB  - The molality-based osmotic coefficients of aqueous mixtures of KBr and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic method at KBr ionic strength fractions y = (0.18328, 0.38241, 0.58031, 0.79186, and 1) and over the ionic strength range (2.5452 to 10.0418) mol . kg (-1), using KCl(aq) and CaCl2(aq) as the reference standard solutions. These experiments were performed using glass sample dishes because preliminary experiments showed that some corrosion of our usual gold-plated silver dishes occurred with dissolution of silver, presumably by "pinhole" corrosion at imperfections in the gold layer. These osmotic coefficients were modeled with an extended form of Pitzer's ion-interaction model equations, both with the usual Pitzer mixing terms and with Scatchard's neutral-electrolyte mixing terms, and with the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale. There are no previously published isopiestic measurements for this ternary system. The present assessment yields mixing parameters for these models. Model parameters for KBr(aq) at T = (298.15 +/- 0.01) K were also evaluated using the present results along with four sets of osmotic coefficients taken from the published literature. For the {yKBr + (1 -y)K2HPO4}(aq) system, the model with five Scatchard mixing terms gave a significantly better representation of the osmotic coefficients than any of the other models and is therefore recommended for calculation of osmotic and activity coefficients.

AB  - The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and 0.83170), over the ionic strength range (2.4958 to 6.0801) mol.kg (1), using KCl(aq) and CaCl2(aq) as the reference standard solutions. These measurements include some new isopiestic results for the KNO3(aq) binary system extending slightly into the oversaturated (supersaturated) molality region from (2.1973 to 4.1295) mol.kg (1). Our new experimental results were modeled with an extended form of Pitzer's ion-interaction model equations, both with the usual Pitzer mixing terms and with Scatchard's neutral-electrolyte mixing terms, and with the Clegg-Pitzer-Brimblecombe equations based on the mole-fraction-composition scale. There are no previously published isopiestic measurements for the {yKNO(3) + (1 - y)K2HPO4}(aq) system. The present assessment yields NO3 - HPO42 mixing parameters for these models that are needed for modeling the thermodynamic activities of solute components of natural waters and other complex aqueous electrolyte mixtures. Model parameters for KNO3(aq) at T = (298.15 +/- 0.01) K were also evaluated using the present results along with critically-assessed osmotic coefficients taken from the published literature. Thermodynamic properties of the saturated solution were calculated using published solubilities of KNO3(cr) in water at T = 298.15 K and the evaluated ion-interaction model parameters for KNO3(aq).
