AbstractThe component solubility of HCl-MgCl2-H2O System at 50 degrees C was calculated by using Pitzer's ion-interaction model and its extended HW model. The values of the parameters of beta((0)), beta((l)), C-phi of HCl and MgCl2 were obtained from optimization of the literature data, and theta(MgH) and psi(MgHCl) were derived by coupling activity coefficient with solubility data. The comparison between the results by using the parameters derived by us and the results by adopting the parameters coming from the literature indicated that the parameters obtained from the system of ionic strength of 0.1 mol/kg <= I <= 5 mol/kg (MgCl2 center dot 6h(2)O was the solid phase) were not suitable to predict the solubility of the system of ionic strength of 14 mol/kg. This study could provide the theoretical basis for extracting LiCl and MgCl2 center dot 6H(2)O from salt lake brine by using HCl as the salting out reagent. (C) 2006 Elsevier Ltd.
