Microwave-enhanced thermal decontamination of soil
Article Abstract:
The results of the bench-scale and pilot-scale testing of microwave heating of contaminated soils showed that the technique is feasible especially in contaminated soils high in organic content. The technique relies on heating the soil and the subsequent volatilization of contaminants for its remediation properties. The effectivity of using microwave energy stems from the use of temperature that does not exceed 100 degrees Centigrade. The use of microwave heating in remediation must be supplemented with the knowledge of the soil's dielectric and physico-chemical properties as well as the chemical properties of the contaminant.

Soil retention of trifluoroacetate
Article Abstract:
Trifluoroacetic acid (TFA), a byproduct resulting from the degradation of compounds such as hydrofluorocarbons and hydrochlorofluorocarbons, accumulates in soil, to varying degrees. Soils that are especially high in organic matter or that contain high amounts of aluminum or iron appear to retain TFA the most, when compared to other types of soil. The accumulation of TFA also increased as the soil pH decreased. The consequences of TFA accumulation in soils is yet to be determined.
