摘要：
The influence of inorganic salts on sodium dodecyl benzene sulfonate (SDBS)/butanol/octane/water microemulsion system was investigated by changing the type of salts. Increasing cationic charge concentration of various salts in an anionic surfactant microemulsion system promoted changes in the microemulsion phase behavior from lower phase (Winsor I) microemulsion through middle phase (Winsor III) toward upper phase (Winsor II) microemulsion. While for different inorganic salts, optimum salinities were different. Six groups of salt mixture systems were investigated. There was a linear relationship between efficiency parameter of salt mixtures and their composition, in other words, the influence of salt mixtures could be predicted by studying efficiency parameter of single inorganic salts. By using efficiency parameter as the medium, the relationship between optimum salinity of single salts and their mixtures was deduced, and could be used to predict the influence of salt mixtures. The prediction results coincided well with the experimental results. ©All Rights Reserved
