Title : Surfactants enhanced soil remediation
Abstract:
Surfactants are a class of amphiphilic substances that simultaneously include hydrophilic and hydrophobic components in their molecular structure. Surfactants' distinctive molecular structure makes it possible to increase the solubility of soil pollutants in water, particularly those hydrophobic organic molecules. For soil remediation, a range of surfactants, including anionic, cationic, zwitterionic, and nonionic surfactants, have been investigated and/or used. In the general process for an ex-situ soil cleaning where surfactant aqueous solution, first the contaminated soil that has been excavated is pretreated, combined with water that contains surfactants, and stirred. Once wash, the clay particles are left to settle out, and the eluents can be extracted and recycled for the next round use exploitation. Ex-situ soil washing enables the very economical return of clean coarse fractions of soil to the site while treating a wide range of influent contamination concentrations. Another method for practical application is in-situ soil flushing with surfactant eluents. Through injection wells, flushing solutions, such as liquids containing surfactants, are injected into the contaminated region. By solubilization (for example, the production of micelles with the aid of flushing solutions) or chemical interactions, the soil pollutants are mobilized. The contaminant-bearing fluid is collected and brought to the surface after it has passed through the contamination zone for disposal, recirculation, or on-site treatment and reinjection. Soil washing is one of the few available treatment methods that can completely extract radionuclides, organics, and heavy metals from polluted soils. For soil washing or other remedial treatments, such as surfactant-enhanced bioremediation, surfactant-enhanced phytoremediation, and surfactant-enhanced electrokinetic remediation, surfactant is a frequently used ingredient.
