Densities and Viscosities of Polyethylene Glycol 6000 + Triammonium Citrate + Water Systems

The densities and viscosities of binary and ternary solutions of the aqueous two-phase systems created by the
polyethylene glycol 6000 + triammonium citrate + water system were measured at different temperatures [(25,
30, 35, 40, and 45) °C] and correlated with empirical equations. The density data were compared with those
available in the literature. The density data show a linear variation with the mass fraction of the polymer for all
temperatures. The density and viscosity of the top and bottom phases were also measured and reported.
