Abstract

This activity will result in a commercialized version of a field-portable instrument for performing supercritical fluid extraction (SFE) with on-line Fourier transform infrared (FT-IR) detection. The Energy & Environmental Research Center (EERC) has developed an SFE field-portable method for quantitatively extracting organic pollutants (e.g., polycyclic aromatic hydrocarbons [PAHs], polychlorinated biphenyls [PCBs], total petroleum hydrocarbons [TPHs]) from soils and sludges under U.S. Environmental Protection Agency (EPA) funding. FT-IR is a detector that can yield quantitative and compound-class information for organic pollutants and is excellent for survey uses, since virtually all organic compound classes can be monitored. A laboratory prototype SFE-FT-IR instrument has been developed at the EERC and the University of North Dakota (UND) Department of Chemistry. The commercial instrument will be field-portable (requiring only generator electricity) and able to extract and measure organic pollutants from soils and sludges, identify the compound classes present, and provide quantitative or semiquantitative results at detection limits relevant to regulatory needs (e.g., parts per million). The SFE-FT-IR approach is particularly advantageous for very hazardous samples (e.g., determination of organics in solids contaminated with radioactive components), since SFE-FT-IR analysis generates no waste solvents. The instrument will also be configured to allow collection of {open_quotes}positive{close_quotes} extracts formore »« less

Technical Report

Several field-portable (e.g., gas chromatrography (GC), gas chromatography-mass spectrometry (GC-MS)) instruments are available for the measurement of organic pollutants. However, solid samples such as soils, sludges, and sediments must first be extracted before analysis can be performed. Conventional extraction methods based on liquid solvent (e.g., Soxhlet extraction) are not practical in the field because of the large volumes fo solvents required as well as clumsy apparatus and glassware. However, supercritical fluid extraction (SFE) has been demonstrated in several studies by the Energy & Environmental Research Center (EERS) to extract a broad range of organic pollutants from soils and sediments successfully.more »« less

Subtask 1.12 - Solid-Phase Microextraction (SPME) Coupled with Optical Spectroscopy for Near-Real-Time Determination of Fuel and Related Pollutants in Water Samples: Semi-annual report, July 1--December 31, 1996

Technical Report Hawthorne, S B

The measurement of organic pollutants in water requires that samples be collected, transported to a laboratory, extracted (usually with large volumes of hazardous chlorinated solvents), and analyzed using chromatographic techniques. Such limitations make rapid determinations in the field (e.g., for emergency response and/or for survey investigations) very expensive with analytical turnaround times requiring several days. Similar limitations exist for the collection and analysis of organic pollutants in air. An alternative approach is being developed at the Energy {ampersand} Environmental Research Center (EERC) that has been demonstrated to yield good sensitivities (ppb to ppm) and be easily adapted for rapid (lessmore »« less

Subtask 1.17 - Subcritical Water Extraction of Mercury From Soils and Sediments

Technical Report Hawthorne, Steven B

The U.S. Environmental Protection Agency (EPA) "National Sediment Quality Survey" lists the top pollutants responsible for toxicity in watersheds as 1) PCBS (polychlorinated biphenyls), 2) mercury, and 3) other organics such as PAHs polycyclic aromatic hydrocarbons) and pesticides. In addition, these same pollutants are major contributors to chemical pollution on U.S. Department of Energy (DOE) and other contaminated sites (e.g., industrial sites and harbors). An ideal remediation method would allow cost-effective removal of both organic and mercury contamination using a single process. The Energy & Environmental Research Center (EERC) has demonstrated that controlling the temperature (and to a lesser extent,more »« less

This report summarizes the work performed by the Energy & Environmental Research Center (EERC) under the U.S. Department of Energy Jointly Sponsored Research Program JV Task 92, which is a continuation of JV9. Successful studies performed in 1999 through the end of 2008 demonstrated the potential for using selective supercritical fluid extraction (SFE) and a solid-phase microextraction (SPME) method for measuring sediment pore water polycyclic aromatic hydrocarbons (PAHs) to mimic the bioavailability of PAHs from manufactured gas plant and aluminum smelter soils and sediments both in freshwater and saltwater locations.
