چكيده فارسي :
In This work, the thermodynamic properties of (NH4SCN+BuOH+H2O) system were experimentally studied by emf measurements at 25 ºC. Mean activity coefficients and Gibbs energies of transfer of NH4SCN in mixed-solvent systems containing (0, 0.05, 0.1, 0. 15 and 0.2) mass fractions (w) of BuOH in water were determined using the Pitzer ion-interaction model. The results of optimization by Pitzer model were meaningful .
