Effect of Nonaqueous Phase Liquids on the Phase Behavior of Microemulsion Formed by n-Dedocyl Polyglucoside

Surfactant-enhanced aquifer remediation has gained more and more attention. In this article, the n-dodecyl polyglucoside based middle phase microemulsions have been studied with the Winsor phase diagram method. The phase types, phase volumes, alcohol window, optimum alcohol concentration, and region of the middle-phase microemulsion were observed. The results show that the increase in n-butanol concentration causes a series of phase inversion Winsor I (2) ? III(3) ? II(). The larger the concentration of C12G1.46, the larger the solubilization power of the microemulsion system. The solubilization power of the microemulsion system for chlorocarbon is larger than that for alkanes.
