| Abstract: | The content of propyl alcohol and ammonia sulfate after the precise phase separation was determined by the investigation of the propyl alcohol-ammonia sulfate-H2O system.The compositions of top and bottom phase had been obtained by determination of electrical conductivity and refractive index.Propyl alcohol was rich in the top phase and the ammonia sulfate was rich in the bottom phase.The aqueous two phase systems were applied in the pigment separation of the tomato and the lemon rind to get the good separa... |
