Abstract：Thermodynamical models of aqueous two-phase liquid equilibria include an osmotic virial expanding equation for describing osmotic behaviour of liquid mixture, a strictly regular solution with emphasis that liquid has order in near distance and the structure of liquid is looked as lattice, a free volume theroy with for linking thermodynamical property of liquid with strength between molecules. Correlation methods are also described. It is difficult for the models to meet polymer-polymer system and polymer-salt system at the same time using in biological active-substance. It is necessary to further research.
