Abstract
A thermodynamic model is developed and shown to reliably simulate the speciation of the quaternary H2SO4–Fe2(SO4)3–FeSO4–H2O system through a wide range of solution compositions and temperatures (25 °C–150 °C). The main species involved (including H+, Fe2 +, Fe3 +, SO42 −, HSO4−, FeHSO4+, FeSO4°, FeHSO42 +, Fe(SO4)2−, FeSO4+, Fe2O3 and H2O) were investigated, and their thermodynamic data were collected and critically assessed to evaluate their...
