Experimental study demonstrates the degradation of sulfur mustard on potassium fluoride-alumina supports, indicating viable pathways for solid-phase chemical warfare agent decontamination.
The degradation of the warfare agent sulfur mustard (HD) adsorbed onto KF/Al(2)O(3) sorbents is described. These processes were explored by MAS NMR, using (13)C-labeled sulfur mustard (HD*) and LC-MS techniques. Our study on the detoxification of this blister agent showed the formation of nontoxic substitution and less-toxic elimination products (t(1/2) = 3.5-355 h). Interestingly, the reaction rates were found to be affected by MAS conditions, i.e., by a centrifugation effect. The products and the mechanisms of these processes are discussed.
