Modeling of ionic equilibria of trace metals (Cu2+, Zn2+, Cd2+) in concentrated aqueous electrolyte solutions at 25 °C

“…e From Na 2 CO 3 (H 2 O) 10 (natron) solubility in NaCl [15], NaNO 3 [47], NaOH [49], and Na 2 SO 4 [48] solutions. f From pK(HCO − 3 ⇔ H + + CO 2− 3 ) in NaClO 4 [32] solutions. g From NaHCO 3 (nahcolite) solubility in NaCl [17], NaNO 3 [46], Na 2 SO 4 [44], and Na 2 CO 3 [45] solutions.…”

“…Right upper panel: second dissociation constant of sulfuric acid in NaCl [29] and NaClO 4 (hollow circles: [30]; box: [31]) solutions. Bottom: first (left panel) and second (right panel) dissociation constants of carbonic acid in NaClO 4 [4,32], NaCl and KCl [5] solutions (values for dissociation constants of carbonic acid in KCl solutions were interpolated from data measured at 0, 50, and 75 • C).

“…Some of them were calculated from activity data for single electrolytes [12][13][14] and from potentiometric [4,5,21,[26][27][28][29][30][31][32] and solubility [15][16][17][18][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] studies. Uncertainty is conditioned mainly by insignificant variation of the parameter b ij with ionic strength and, in the majority of cases, specifies applicability of the model to the description of experimental data.…”

Injection of CO2 with H2S and SO2 and Subsequent Mineral Trapping in Sandstone-Shale Formation

“…A critical evaluation of the data contained within these literature sources in conjunction with appropriate data drawn from specific aqueous speciation studies, e.g. Frydman et al (1958), Nilsson et al (1958), Rengamo et al (1958), and Rai et al (1991), should permit satisfactory data to be obtained for the thermodynamic properties of hannebachite. An evaluation of information provided on the partial solid solution series between gypsum and CaSO 3 .2H 2 O by Takahashi (1978, 1979) and Takahashi and Setoyama (1982), and the partial solid solution between hannebachite and CaSO 4 .0.5H 2 O by Jones et al (1977a,b) might also allow for the formulation of appropriate solid solution models to predict precipitation behavior in aqueous sulfitesulfate solution mixtures.…”

“…Most of the earlier literature is summarized by Lutz (1986), and includes notable contributions by Schwartz and Muller-Clemm (1921), Ghurd et al (1935), Gishler and Maass (1935a,b), Otuka (1939a,b), Frydman et al (1958), Nilsson et al (1958), Rengamo et al (1958), Engelhardt (1962), Templeton et al (1963) and Rodin and Margules (1983a,b). A very precise determination of the solubility of CaSO 3 .0.5H 2 O at 25°C was published subsequently by Rai et al (1991).…”
