@article{(Open Science Index):https://publications.waset.org/pdf/4396, title = {Phase Equilibrium in Aqueous Two-phase Systems Containing Poly (propylene glycol) and Sodium Citrate at Different pH}, author = {Farshad Rahimpour and Ali Reza Baharvand}, country = {}, institution = {}, abstract = {The phase diagrams and compositions of coexisting phases have been determined for aqueous two-phase systems containing poly(propylene glycol) with average molecular weight of 425 and sodium citrate at various pH of 3.93, 4.44, 4.6, 4.97, 5.1, 8.22. The effect of pH on the salting-out effect of poly (propylene glycol) by sodium citrate has been studied. It was found that, an increasing in pH caused the expansion of two-phase region. Increasing pH also increases the concentration of PPG in the PPGrich phase, while the salt-rich phase will be somewhat mole diluted.}, journal = {International Journal of Chemical and Molecular Engineering}, volume = {3}, number = {11}, year = {2009}, pages = {621 - 624}, ee = {https://publications.waset.org/pdf/4396}, url = {https://publications.waset.org/vol/35}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 35, 2009}, }
