SSMAS NMR Study of HD, GD, and VX on Carbon Fiber Textiles for Wipes; Final rept. Oct 2005-Dec 2007

摘要

The C13 and P31 SSMAS NMR were used to study the degradation of HD, GD, and VX on a mesoporous and a microporous carbon fiber textile. The degradation of HD was faster than on ambient sand, concrete, limestone, and asphalt, and comparable to moist sand, concrete, limestone, and asphalt, forming toxic H-2TG and non-toxic TDG. The HD absorbed on both fiber textiles. The VX degradation rate on the carbon fiber textiles was comparable to sand, although the product was the toxic compound diethyl dimethylpyrophosphonate, rather than non-toxic ethyl methylphosphonic acid, as on sand. The VX absorbed on the mesoporous, but not the microporous fiber textiles. The GD absorbed into the fiber textiles and degraded to non-toxic ethyl methylphosphonic acid within a week.
