Solubility Experiments and Thermodynamic Modeling for the Quaternary System MgF₂–MnF₂–MnSO₄–H₂O and Its Subsystems at 298.15 K

Abstract

The solubility data of the MgF 2 −MnF 2 −MnSO 4 −H 2 O quaternary system and its subsystems are crucial for the removal of magnesium ions from a MnSO 4 aqueous solution as the MgF 2 precipitate. However, these data recorded at 298.15 K have not been reported, except for the MnF 2 −MnSO 4 −H 2 O system. In this study, the solubility isotherms of the
