Development of Sampling and Preservation Techniques to Retard Chemical and Biological Changes in Water Samples
Abstract
A protocol was defined for the preservation of 12 munitions (Dinitrophenol DNP; Cyclotrimethylene trinitramine, RDX; 1,3,5-Trinitrobenzene, TNB; 1,3-Dinitrobenzene, DNB; 2,4-Dinitrotoluene, 2,4-DNT; Trinitrotoluene, TNT; 2,4,6-Trinitrophenylmethylnitramine, Tetryl; Diphenylamine, DPA; Nitrobenzene, NB; 2,6-Dinitrotoluene, 2,6-DNT; Nitroglycerin, NG; and Picric Acid, PA) in water samples. The samples were preserved by adding acetonitrile to achieve a 10% solution; the adjusting of the pH to 3.5 with glacial acetic acid; removing sediment by centrifugation; storing in amber glass bottles (cleaned according to specified instructions) sealed with Teflon cap liners; refrigerating at 4C; and maintaining in the dark. The effectiveness of the protocol was demonstrated for munitions fortified in tap water and monitoring well water samples, and sediment-deionized water mixtures.
