| Abstract: | The equation of state for aqueous electrolytes based on perturbation theory is established. By using the water molecular parameters and Pauling diameters of canons and anions without any additional parameters, the densities of 9 aqueous electrolyte systems (NaCl, CaCl2,KCl, LiCl, BaCl2, MgCl2, NaBr, Na2SO4 and MgSO4) at high pressure and temperature are predicted. The predicted accuracy of densities is satisfactory. The accuracy can be improved by using the fitted canon diameter instead of Pauling diameters. |
