摘要：
Water activities in the ternary LiNO3+KNO3+H2O system and its sub-binary systems have been measured by the isopiestic method at 273.1 and 298.1 K. The measured results were treated by a Pitzer-Simonson-Clegg thermodynamic model, from which the predicted solubility isotherms were compared with the experimental results. Based on this comparison, the reliability of the measured results was discussed. The measured results help in predicting the phase diagram of the ternary system, as well as other multi-component systems based on the ternary system.
