Résumé

In this study we proposed a complete methodology to determine a full set of Pitzer interaction parameters for the BaCl2-H2O electrolyte system. The parameters are allow representing the osmotic coefficient, the solution heat capacity and the solution density for temperatures ranging from 0 to 90°C and concentrations up to 2 mol.kgw-1. The work done on the binary BaCl2 system can be extended to many other systems, if sufficient experimental data are available to fully parameterize the systems.
