The contribution due to long-range interaction for the potential difference and its variation with the composition is studied for the polyethylene glycol (PEG) 2000-Sodium Citrate-Water-based ATPS (Merck, Germany). The developed correlation for the potential difference with concentration shows a satisfactory prediction of the phase equilibrium for the present system. © 2014 Taylor and Francis Group, LLC. date: 2014 type: Article type: PeerReviewed identifier: Perumalsamy, M. and Murugesan, T.
