Decontamination of oil-contaminated sand using anionic
The intermediate structure (i.e., ethylene oxide: EO) in the SDHS and C12-14Ej is an influent parameter in the surfactant selection for soil remediation. The less EO group in the surfactants, the better sand was decontaminated. The microemulsion types (i.e., I, II, and III) also affected the soil washing/flushing performance.
