Remediation of disel oil-contaminated soil using a two-liquid phase(TLP) system

Abstract

Soil contamination by diesel oil raises a serious environmental threat. Diesel oil is the complex mixture composed of straight and branched alkanes, cycloalkanes, monoaromatics, and polyaromatics. Although the content of polyaromatics in diesel oil is low, they are potentially carcinogenic and genotoxic. Due to little polyaromatics and complexity of diesel oil, soil contaminated by diesel oil is difficult to treat using common remediation technologies. Two-liquid phase (TLP) system can remove pollutants from contaminated soil using the water-immiscible liquid which can dissolve much more hydrophobic compounds than surfactants. In this study, the feasibility of TLP system for the …
