Abstrakt

Literature data on and own measurements of phase equilibria in the systems aluminium ammonium sulfate - ammonium sulfate - water, aluminium ammonium sulfate - aluminium sulfate - water, aluminium ammonium sulfate - sulfuric acid - water, and aluminium ammonium sulfate - ammonium ferric sulfate - water were elaborated. Data correlation using the method of relative activity coefficient expansion made it possible to work up the data in a wide range of temperatures. Hydration analysis showed different behaviour of the systems.
