摘要：
This study was based on the detergent properties of microemulsions on crude oil-contaminated soils. Were used as the ionic surfactant sodium dodecyl sulfate (SDS) and sodium dodecyl benzene sulfonate (SDBS). Kerosene was used as the oil phase, and as additives, 1-pentanol and 1-butanol. Microemulsions as systems were evaluated on a soil contaminated with oil from the Yaracal district, Falcon State. The systems evaluated were put in contact with soil, shaking mechanically for 04 hours. The microemulsion with SDS, was found to be the highest performance, with 95.43 %, a result confirmed by infrared spectroscopy technique, which were characterized with soil samples before and after treatment with the systems surfactants-oil-water. This procedure can be an alternative remediation for areas affected by oil spills, and can even be applied in cleaning oil in various solid substrates.
