Measurement and correlation of phase diagram data for polyoxyethylene (10) lauryl ether and potassium hydroxide/potassium carbonate/potassium phosphate aqueous two-phase systems at 298.15 K

▸ The phase diagrams of Brij35-potassium salts ATPSs were determined experimentally. ▸ The LLE data were obtained by experimental and calculated method respectively. ▸ The experiential equations were used to correlate the binodal data and LLE data. ▸ The effect of salt on the binodal curve for the studied systems has been discussed. ▸ The phase-separation ability of Brij35 is more powerful comparing other polymer.
