Abstract: 

Extraction of biomolecules (as enzymes and proteines) by the use of two aqueous phase and conventional chemical industry instrument is a new phenomenon. In this research, phase diagram of a three -component system consisting of (Na2S03, PEG 1000, H2O) and also concentration of PEG 1000 and Na2SO3 were measured respectivley by the use of refractometer and atomic adsobtion spectrophotometer. Phase diagram of this system was achieved with {Ira wing PEG 1000 weight percent vs. Na2SO3, weight percent ill two phase and at some temprature as 25° C, 35° C 45°C. Three angular phase diagram of the tree - component system consisting of (H2O, Na2S03, PEG 1000) component system can be applied in biotechnology for seperation of biomolecules.
