A kind of leacheate of recovery technique is widely studied and applied.Contaminated soil, table are eluted using surfactant solution
Face activating agent consumption is big, and remaining amount of surfactant is more in the soil, and for this problem, microemulsion is in organic dirt
It is gradually applied in terms of dye soil remediation.
Microemulsion is by water（Aqueous solution）, oil, surfactants/cosurfactants spontaneously form under proper proportion
Dispersion particle diameter is nanoscale is thermodynamically stable, transparent or semitransparent system of optical isotropy.Microemulsion overcomes
Conventional emulsions are easy split-phase and unstable problem, have ultralow interfacial tension and extremely strong solubilising and emulsifying capacity, as
Important microenvironment medium, one of feature are the ability of solubilized indissoluble organic pollutant much larger than micellar solution.With microemulsion
Instead of surfactant solution as leacheate, it can effectively enhance the removal rate of soil organic pollutant.Surfactant conduct
One of main component of conventional microemulsions, though it is reduced compared to the dosage with surfactant directly as leacheate,
When for eluting, still remain aequum is larger, surfactant is at high cost, part of the surface activating agent residual to soil environment produce
The disadvantages of raw adverse effect.
CN104998897A discloses a kind of method that surfactant compound repairs petroleum hydrocarbon contaminated soil, and this method is adopted
It is compounded with nonionic surfactant with anionic surfactant, amount of surfactant consumption is big, surfactant is easy
Residual；CN105176540A discloses a kind of preparation method of the leacheate of repairing organic polluted soil, the leacheate ingredient
Complexity, and operating procedure is more；CN104826863A disclose it is a kind of using ultrasound and surfactant removal soil in benzo
The method of pyrene, this method use surface active agent solubilization BaP, reuse deionized water and carry out at ultrasound to soil after processing
Reason, the surfactant of removal residual in the soil, this method can only carry out dystopy soil remediation, and treating capacity is smaller, cost
It is higher.
