چکیده In this paper, salting-out principle was used to produce new types of polymerbased aqueous biphasic systems (ABS). For this purpose, the process of cloud point of polypropylene glycol 1000, a temperature sensitive polymer, is in pure water and in aqueous solutions with various molecules of salts ( Na2CO3,Na2SO4, Na3Cit,K3Cit, NaCl DTAB, SDS) and to be investigated hydrophilic and hydrophobic ionic liquids ) with a specific moleality 0.05 ( C2mimBr, C4mimBr, C8mimBr, C8mimCl, C4mimBF4, C4mimPF6). The thermodynamic quantities of the clouding process have been calculated and also the salt effect of stabilization (salting out/ salting in) has been evaluated using the Setschnow equation. Observations indicate that salts (Na2SO4, Na3Cit, K3Cit, Na2CO3) show a reduce clouding temperature [1-3].
