英文摘要	Component solubility in HCl-LiCl-H2O- HCl-MgCl2-H2O and LiCl-MgCl2-H2O systems of high ionic strength at 0 degreesC and 20 degreesC are calculated by using the Pitzer's ion-interaction model and parameters derived from a least-squares optimization procedure which couples activity coefficient with solubility data. Excellent agreement with experimental solubility for ternary mixtures indicates that the model can be successfully used to predict the component solubility of salt lake brine systems that contain high concentration of LiCl. For all of the systems containing a high concentration of HCl, measurements of the activities of the complex compounds are not available, hence, the evaluation of the values for the mixing parameters (theta) (MN) and psi (MNX) relied on solubility data in subsystems. The prediction also indicates that the parameters used do not vary linearly with the temperature, thus the algorithm used in order to calculate the parameters of LiCl at different temperatures is presented here. Based on the predictions of the solubility, the solubility curves of six ternary systems are constructed.
