Based on the literature data and the pitzer equation, the parameterization of HCl-LiCl-H 2 O system was carried out. The single-salt parameters of HCl and LiCl at 0 ° C and 20 ° C, Three ion interaction parameters a total of 10. The obtained parameters are used to predict the solubility of the system at 0 ° C and 20 ° C. It provides the most basic parameters for calculating the physico-chemical properties of brine system. The prediction of solubility of Pitzer model from room temperature to other temperatures is of great significance to the extraction of LiCl by acid method from salt lake resources. The computer technology applied to the experimental research, reducing the cumbersome experimental determination
