摘要：
The solubilities of three sulfate salts (Na2SO4, K2SO4, MgSO4) and two chloride salts (NaCl, KCl) with a second salt in water were measured at 313 K. The ternary systems studied were water + NaCl + KCl, water + NaCl + Na2SO4, water + KCl + K2SO4, water + Na2SO4 + K2SO4, water + K2SO4 + MgSO4, and water + Na2SO4 + MgSO4. The solubilities of two salts in the ternary systems were obtained, and the data were used to obtain the eutectic concentrations of the ternary systems. The solubility data were also predicted by the electrolyte-NRTL model, in which parameters were obtained from the binary data. The qualitative effect of the second salt on the solubility of the first salt in water is discussed.
