چکیده انگلیسی
The extended Pitzer model has been used for calculation and correlation of the ternary NaCl-H2O2-H2O, Na2SO4-H2O2-H2O and the quaternary Na2SO4-NaCl-H2O2-H2O systems at the temperature of 288.15Â K. The necessary thermodynamic functions (binary and ternary parameters of interaction and thermodynamic solubility products) have been derived from a least-squares optimization procedure with couples activity coefficient with solubility data and the theoretical solubility isotherms has been plotted. Good agreement with experimental solubility for ternary and quaternary mixtures indicates that the model can be successfully used to predict the component solubility of the electrolyte-nonelectrolytes-water systems containing peroxide. In addition, the Pitzer interaction parameters and the thermodynamic solubility product of 4Na2SO4â
2H2O2â
NaCl and Na2SO4â
0.5H2O2â
H2O at 288.15Â K are obtained.
