Effects of temperature and salinity （Na2SO4） on the distribution of TX114 concentration were also investigated. Differing from the nonionic surfactant C12E10, the distribution of TX114 is sensitive to the temperature, and it is observed that the TX114 concentration in the aqueous phase （Caq） does not depend on the initial TX114 concentration apparently at 45℃, and the Caq decreases with an increase of NazSO4 concentration. Low initial TX114 concentration in unclouded solutions, high Na2SO4 concentration, and temperature are suggested to control the surfactant loss in large-scale cloud point extraction applications.展开更多
