Interaction Theories and Kirkwood-Buff Integrals of PEG

Our studies concerning Gij, thus establishes that in PEG aqueous solutions hydrophobic hydration and hydrophobic interaction are of importance in determining the solution properties.Analysis of the applications McMillan-Mayer theory of solutions to the activity data, indicate that in aqueous solutions, in the solubility range both hydrophobic interaction as well as hydrophobic hydration processes are operative. In infinitely dilute solution hydrophobic hydration and at finite concentrations of PEG’s, the additional hydrophobic interactions determine the overall thermodynamic properties of solutions. Our studies concerning Gij, thus establishes that in PEG aqueous solutions hydrophobic hydration and hydrophobic interaction are of importance in determining the solution properties.
