Determination of munitions in water using macroreticular resins
A simple procedure has been developed for the determination of munitions present in water at levels as low as 0.1 /sup +/g/L. The method uses 60-80 mesh XAD-4 for extraction, followed by elution with 20 mL of ethyl acetate, concentration of the eluate, separation by capillary GC, and detection using electron capture. Contrived and field samples containing nitrobenzene, 1,3-dinitrobenzene, 1,3,5-trinitrobenzene, 2,4-dinitrotoluene, 2,6-dinitrotoluene, 2,4,6-trinitrotoluene (TNT), and 1,3,5-trinitrohexahydro-1,3,5-triazine (RDX) have been tested successfully. The XAD-4 extraction in the field reduced the cost of transporting water samples to the laboratory where additional savings occurred because less solvent was used to elute the resin than was required for solvent extraction. Adsorption onto particulate matter, association with humic acids, resin capacity, resin polarity, and incomplete dissolution were examined as the most likely causes of the low recoveries for RDX when XAD-2 and XAD-7 resins were used. 10 references, 5 tables.
