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