| Abstract: | The aqueous two-phase system ( ATPS) of mixtures of anionic surfactant Sodium Dodecyl Sulfonate (SDS) and cationic surfactant Cetylpyridine chloride (CPC) was studied. The phase diagrams at different temperatures were measured. The influence of ratio, concentration, temperature and the addition of salt sodium chloride ( NaCl) on the aqueous two-phase (ATP) regions was obtained. The relationship among volume, density and concentration in ATP was investigated. And the microstructures of ATP were observed by microscope. |
