摘要：

The Pitzer ion-interaction extended by Harvic and Weare was applied to predict the solubility isotherms of reciprocal quaternary systems in which mixed crystals are formed. On the basis of data concerning the binary and ternary subsystems, the four components systems Rb+, Cs+/Cl-, SO (4) (2-) -H2O, and K+, Cs+/Cl-, SO (4) (2-) -H2O were investigated at 25A degrees C.The results of calculation can be used to model salt crystallization during the concentration of brines.
