| Zusammenfassung: | The solubility isotherms were determined for the NH4NO3 + NaVO3 + NH4VO3 + NaNO3 + H2O system at 293 and 303 K. Based on these isotherms, the maximum yields have been determined for the conversion of ammonium nitrate to ammonium meta-vanadate. The location of the triple points P1 and P2 has been determined on the equilibrium plots prepared as the planar projection, according to the Jänecke method. The results are necessary for determining the optimal conditions for utilization of post-filtration lye obtained from the soda−chloride−saltpeter (SCS) method of soda ash production. |
