The isopiestic method was used to determinate isopiestic molality and osmotic coefficients in single salt solutions of LiCl-H2(molality range from 0.5 to 9.0 mol•kg -1 ), CaCl2-H2O(molality range from 0.35 to 5.2 mol•kg -1 ) and multisalt solution LiCl-CaCl2-H2O(ionic strength range from 0.5 to 15.7 mol•kg -1 ) at 298.15K, from which Pitzer's interaction parameters of single salt ,mixed salts of the systems were obtained. The mean ionic activity coefficients of LiCl、CaCl 2 in pure and mixed solutions were reported.
