Remediation of Elemental Mercury Using in Situ Thermal Desorption …
In situ thermal desorption (ISTD) is a soil heating method that simultaneously applies heat and vacuum to the subsurface at temperatures up to 600 °C. As the soil is heated, the vapor pressure of the contaminant increases allowing mass transfer to the gas phase and extraction from the soil using vacuum wells. The overall goal of this research is to …

Best management practices for minimizing undesired effects of thermal
Although thermal desorption (TD) and soil washing (SW) can remediate contaminated soils quickly and reliably, energy-intensive nature and potential to damage soil properties of these remediation techniques must be considered in the context of green and sustainable remediation. This review concluded that incorporating best …
A Citizen's Guide to Thermal Desorption
Thermal desorption removes organic contaminants from soil, sludge or sediment by heating them in a machine called a "thermal desorber" to evaporate the contaminants. Evaporation changes the contaminants into vapors (gases) and separates them from the solid material. Many organic contaminants can be removed by thermal desorption.
THERMAL DESORPTION Introduction and Principles
Thermal Desorption • Thermal desorption is a simple extension of the technique of gas chromatography (GC) • It involves the use of heat and a flow of inert gas to extract volatile and semivolatile organics from a solid sorbent or other sample matrix • The analytes are extracted into the stream of inert gas and are

Thermal Desorption
Thermal desorption is an extraction technique which utilizes a flowing gas to extract a small heated solid or liquid sample. This process occurs during injection in GC systems and, in some cases, the approach is useful to separate thermally the analyte from the matrix for direct analysis in a flowing gas stream.

The desorption temperature needs to be high enough (typically 200 C) to extract all the –300 analytes, but not so high as to generate artefacts from thermal degradation of the sorbent. The desorption volume should be as small as possible but su cient. ffi. enough to extract all the analytes from the sorbent.
