Abstract

Solubility modeling in the binary system Fe(NO₃)₃–H₂O, Co(NO₃)₂–H₂O and the ternary system Fe(NO₃)₃–Co(NO₃)₂–H₂O is presented. The extended UNIQUAC model was applied to the thermodynamic assessment of the investigated systems. The model parameters obtained were regressed simultaneously using the available databank but with more experimental points, recently published in the open literature. A revision of previously published parameters for the cobalt ion and new parameters for the iron(III) nitrate system are presented. Based on this set of parameters, the equilibrium constants of hydrates are determined. The model represents the experimental data with good accuracy from the freezing point region to the boiling points of the solutions.
