Correlation and Prediction of Thermal-Properties and Phase-Behavior for a Class of Aqueous-Electrolyte Systems
An extended UNIQUAC model is used to describe phase behaviour (VLE, SLE) and thermal properties (heat of mixing, heat capacity) for aqueous solutions containing ions like (Na+, K+, H+) (Cl-, NO3-, SO42-, OH-, CO3-). A linear temperature dependence of the binary interaction parameters allows good agreement with experimental data in the temperature range 0-110 degrees C.
