Abstract

This report summarizes work that developed a robust solvent extraction procedure for recovery of chemical attribution signature (CAS) compound dimethyl methyl phosphonate (DMMP) (as well as diethyl methyl phosphonate (DEMP), diethyl methyl phosphonothioate (DEMPT), and diisopropyl methyl phosphonate (DIMP)) from painted wall board (PWB), which was selected previously as the exposed media by the chemical attribution scientific working group (CASWG). An accelerated solvent extraction approach was examined to determine the most effective method of extraction from PWB. Three different solvent systems were examined, which varied in solvent strength and polarity (i.e., 1:1 dichloromethane : acetone,100% methanol, and 1% isopropanol in pentane) with a 1:1 methylene chloride : acetone mixture having the most robust and consistent extraction for four original target organophosphorus compounds. The optimum extraction solvent was determined based on the extraction efficiency of the target analytes from spiked painted wallboard as determined by gas chromatography x gas chromatography mass spectrometry (GCxGC-MS) analysis of the extract. An average extraction efficiency of approximately 60% was obtained for these four compounds. The extraction approach was further demonstrated by extracting and detecting the chemical impurities present in neat DMMP that was vapor-deposited onto painted wallboard tickets.

Extraction of Chemical Impurities for Forensic Investigations: A Case Study for Indoor Releases of a Sarin Surrogate

Journal Article Wahl, Jon; Colburn, Heather - Building and Environment

A solvent extraction approach was developed and examined for extraction of targeted organophosphorus compounds as well as nerve agent simulants from painted wallboard (PWB). Painted wallboard was chosen as a substrate due to its presence as large surface area media in an indoor environment that is applicable to a chemical agent release scenario. Three different solvent systems were examined with a 1:1 methylene chloride : acetone mixture having the most robust and consistent extraction for four target organophosphorus compounds (dimethyl methyl phosphonate (DMMP), diethyl methyl phosphonate (DEMP), diethyl methyl phosphonothioate (DEMPT), and diisopropyl methyl phosphonate (DIMP)).

Photocatalytic degradation of organophosphorous compounds in an aqueous suspension of TiO{sub 2}

Conference Garcia, I; Hernandez, M; O`Shea, K

Organophosphorus compounds (i.e. warfare agents and pesticides) are receiving considerable attention due to their high toxicity as pollutants of ground water. These compounds have a phosphorus-carbon bond which is relatively stable and resistant to conventional methods for chemical remediation. One method that is being considered for the treatment of chemically contaminated water is semiconductor photocatalysis. A promising and effective semiconductor currently receiving consideration for such an application is titanium dioxide (TiO{sub 2}). Dimethyl-methyl phosphonate, DMMP, and diethyl-methyl phosphonate, DEMP, were used as models to analyze TiO{sub 2} photocatalyzed decomposition of organophosphorus compounds.

Detection of gaseous organophosphorus compounds using secondary ion mass spectrometry

Journal Article Groenewold, G; Todd, P - Anal. Chem.; (United States)

Molecular secondary ion mass spectrometry (SIMS) has been investigated for sensitivity and selectivity in the analysis of gaseous organophosphorus compounds. Abundant analyte ions were observed when the gaseous organophosphorus compounds were admitted into the secondary ion source, where a matrix was under primary ion bombardment. The best matrix for the detection of dimethyl methylphosphonate (DMMP), trimethyl phosphate (TMP), and diisopropyl methylphosphonate (DIMP) was determined to be polyphosphoric acid. The abundance of secondary analyte ions was observed to be linear with the introduction rate of gaseous analyte. The introduction rate necessary to produce a 3:1 signal-to-noise ratio in the intensity ofmore »« less

Evaluating and modeling the effects of surface sampling factors on the recovery of organic chemical attribution signatures using the accelerated diffusion sampler and solvent extraction

Journal Article Mo, Kai-For; Heredia-Langner, Alejandro; Fraga, Carlos - Talanta

In this study, an experimental design matrix was created and executed in order to test the effects of various real-world factors on the ability of the (1) accelerated diffusion sampler with solid phase micro-extraction (ADS-SPME) and (2) solvent extraction to capture organic chemical attribution signatures (CAS) from dimethyl methylphosphonate (DMMP) spiked onto painted wall board (PWB) surfaces. The DMMP CAS organic impurities sampled by ADS-SPME and solvent extraction were analyzed by gas chromatography/mass spectrometry (GC/MS). The number of detected DMMP CAS impurities and their respective GC/MS peak areas were determined as a function of DMMP stock, DMMP spiked volume, exposuremore »« less

Identification and separation of the organic compounds in coal-gasification condensate waters. [5,5 dimethyl hydantoin, dihydroxy benzenes, acetonitrile]

Technical Report Mohr, Jr., D.; King, C.

A substantial fraction of the organic solutes in condensate waters from low-temperature coal-gasification processes are not identified by commonly employed analytical techniques, have low distriution coefficients (K/sub C/) into diisopropyl ether (DIPE) or methyl isobutyl ketone (MIBK), and are resistant to biological oxidation. These compounds represent an important wastewater-treatment problem. Analytical techniques were developed to detect these polar compounds, and the liquid-liquid phase equilibria were measured with several solvents. A high-performance liquid - chromatography (HPLC) technique was employed to analyze four condensate-water samples from a slagging fixed-bed gasifier. A novel sample-preparation technique, consisting of an azeotropic distillation with isopropanol, allowedmore »« less
