The activity coefficients of KCl and LiCl in KCl-LiCl aqueous mixtures have been measured at 25 ℃ in ionic strength range of 0.1～4.0 mol·kg~(-1). The measurement were made using K-ISE and Li-ISE vs. Cl-ISE in a wide range of compositions from pure KCl to pure LiCl. The data were fitted to Pitzer's equation using regressin method, Pitzer parameters were obtained.
