Phase Equilibria of Na+, NH4+parallel to SO42-, HCO3-, Cl--H2O Quinary System
Equilibria data for the Na+, NH4+parallel to SO42-, HCO3-, Cl--H2O quinary system at 10 degrees C, 30 degrees C and 40 degrees C. were measured, and the phase diagrams at those temperatures. were constructed. Furthermore, the crystallization zones in the phase diagrams are discussed. The results show that the : separation of Na+ and SO42- can be performed at 40 degrees C by adding NH4HCO3.
