Liquid-liquid equilibria in the system H3PO4-KCl-H2O-tri-n-butyl phosphate: experiments and modelling
The liquid-liquid equilibria of the system H3PO4-KCl-H2O-TBP was studied experimentally in the concentration range 0-6 mol/kg. The obtained data were modelled using the Pitzer equation for the aqueous phase and the Sergievskii-Dannus relationship for the organic phase. A fairly good agreement was observed between the model and the experimental data. (C) 2004 Elsevier B.V. All rights reserved.
