摘要：

The phase diagram of the quaternary system LiCl-NaCl-Kl-H2O have been predicted with a Pitzer-Simonson-Clegg thermodynamic model by combining the binary and ternary model parameters, which were determined by simulating reliable experimental data. The predicted phase diagram shows a good agreement with the available experiment data from the literature. The other thermodynamic properties (e.g. water activity) of the quaternary and its sub-ternary systems have been investigated by the model and compared with the experimental data in literature. Significant improvements have been made in comparison with assessments. (C) 2015 Elsevier Ltd. All rights reserved.
