Role of Entrainers in Supercritical Fluid Extraction of Chlorinated Aromatics from Soils
The application of supercritical fluid technology holds considerable potential for removing toxicants from soil. The use of carbon dioxide at temperatures and pressures above its critical point was evaluated for removal of such contaminants as chlorinated pesticides, polychlorinated biphenyls and chlorinated phenols. Experiments were carried out to optimize the extraction parameters and define the role of entrainers under varied matrix conditions.
