Extraction of organic compounds from soils is most commonly done using time-consuming laboratory procedures. Rapid, portable methods for measuring the concentrations of semivolatile organic compounds in the field are needed. This report describes the development of a supercritical fluid extraction (SFE) method using field-portable equipment that completes the extraction in less than 30 minutes and permits on-site quantification of such compounds in soil samples. 10 figs., 34 tabs., 21 refs.
