Abstract:

Pitzer-Simonson-Clegg model was used to simulate the properties of the ternary system CaCl2−KCl−H2O. The Pitzer-Simonson-Clegg binary parameters and mixture parameters for the titled system at 348.15 K were obtained from the reliable experimental osmotic and solubility data. The solubility isotherms of the titled three ternary system were predicted by Pitzer-Simonson-Clegg model and compared with the available experimental data, the agreement is generally good. The solubility isotherms for the titled system CaCl2−KCl−H2O at 348. 15 K were predicted using Pitzer-Simonson-Clegg model.
