Distribution of TX114 between coacervate and aqueous phases in clouding of various initial TX114concentrations was studied.Effects of temperature and salinity(Na2SO4)on the distribution of TX114 concentra-tion were also investigated.Differing from the nonionic surfactant C12E10,the distribution of TX114 is sensitive tothe temperature,and it is observed that the TX114 concentration in the aqueous phase(Caq)does not depend on theinitial TX114 concentration apparently at 45°C,and the Caq decreases with an increase of Na2SO4 concentration.Low initial TX114 concentration in unclouded solutions,high Na2SO4 concentration,and temperature are suggestedto control the surfactant loss in large-scale cloud point extraction applications.
