Pilot-scale subcritical water remediation of polycyclic aromatic hydrocarbon- and pesticide-contaminated soil

Article Abstract:

This study uses subcritical water to remove polycyclic aromatic hydrocarbons and pesticides from soils, and demonstrates that the soils were fertile after toxin removal.

Class-selective extraction of polar, moderately polar, and nonpolar organics from hydrocarbon wastes using subcritical water

Article Abstract:

A study aimed at reducing the use of hazardous organic solvents for analytical- and process-scale separations is presented. The need for alternative fluids has researchers focused their attention to other environmentally-safe solvents such as water. Water in its supercritical state, however, is limited by the high temperature (>374 degrees Celsius) and pressure (>218 atm) requirements. The results of the study show that low temperature water can extract polar organics, while higher temperature water can extract polar and moderately polar organics.
