摘要：

The composition of the interfacial layer and solubilization of the microemulsions containing mixed cationic and nonionic surfactants (C(12)mimBr-Brij35) were studied and compared based on the mass and the number of moles of the surfactants, respectively. As (mole fractions of C(12)mimBr in C(12)mimBr-Brij35 mixture) increases, the total masses of the surfactants () decrease, whereas the total number of moles of surfactants () increases in the interfacial layer. This opposite pattern of change between and against is due to the significant difference in the molecular mass between the two surfactants. The mass solubilization parameter of the microemulsions, , increases and follows a curve that concaves downward as values increase. However, the molar solubilization parameter, , would decrease as increases. The physicochemical properties of the microemulsions are less sensitive to both temperature and salinity.
