Analytical techniques for the detection of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo(5.5.0.05,9.03,11)dodecane
(CL-20) in water and soil are developed by adapting methods traditionally used
for the analysis of nitroaromatics. CL-20 (a new explosives compound) is thermally
labile, exhibits high polarity, and has low solubility in water. These constraints
make the use of specialized sample handling, preparation, extraction, and analysis
necessary. The ability to determine the concentrations of this new explosive
compound in environmental matrices is helpful in understanding the environmental
fate and effects of CL-20; understanding the physical, chemical, and biological
fate of CL-20; and can be used in developing remediation technologies and determining
their efficiency. The toxicity and mobility of new explosives in soil and groundwater
are also of interest, and analytical techniques for quantitating CL-20 and its
degradation products in soil and natural waters make these investigations possible.
