ABSTRACT

The solubility of potassium vanadate(V) and iron(III) vanadate(V) in the system KVO3 + Fe(VO3)3 + H2O within a temperature range from (293.15 to 323.15) K was measured with the method of isothermal saturation of solutions. The total concentration of vanadium and iron ions in solutions was determined using the EDXRF method. The part of the polythermal solubility surface for the investigated system was plotted based on the obtained data. Additionally, the solution density and viscosity was investigated. Knowledge of these data is necessary to assess the possibility of selective precipitation of vanadium and iron compounds from a post leaching solution of the spent vanadium catalyst.
