Title

TREATMENT OF SOIL CONTAMINATED WITH CRUDE-OIL USING BIOSURFACTANTS

Pages

  107-116

Abstract

 Surfactants are amphiphilic molecules consist of a hydrophilic head and a hydrophobic tail. They are the active ingredients found in soaps and detergents with the ability to concentrate at the air-water interface and are commonly used to separate oily materials from a particular media. Surfactants increase the aqueous solubility of non-aqueous phase liquids (NAPLs) by reducing their surface and interfacial tension at air-water and water-oil interfaces. As the interfacial tension is reduced and the aqueous surfactant concentration increased, the monomers aggregate to form micelles. The concentration at which micelles first begin to form is known as the critical micelle concentration (CMC). This concentration corresponds to the point where the surfactant first shows the lowest surface tension. Many physical properties used to characterize surfactants, depend on the CMC such as: emulsion formation, oil solubility, foaming and detergency, interfacial and surficial tensions. These properties may be used to assess surfactant suitability for environmental remediation works such as SOIL WASHING.
