Flow neutralisation of sulfur-containing chemical warfare agents with Oxone: packed bed vs. aqueous solution

Abstract

The oxidative neutralisation of sulfur-containing CWA (yperite and VX simulants) with Oxone has been developped in flow systems. In order to reach full selectivity towards harmless decomposition products, Oxone has...

Array-based chemical warfare agent discrimination via organophosphorus-H2O2 reaction-regulated chemiluminescence

“…[1][2][3] Among these CWAs, organophosphorus nerve agents (OPNAs) that disrupt neurological regulation of biological systems by suppressing organophosphorus cholinesterase are more toxic and frequently used. 4,5 Therefore, the development of simple and sensitive methods for detecting them is essential to prevent humans from WMA threat or terrorist attack. Toward this goal, many analytical methods based on chromatography, mass spectrometry, and spectroscopy have been constructed for the detection of OPNAs or simulants.…”

Soft detoxification of chemical warfare agent simulants and pesticides under pressure

“…Recently, continuous flow reactors have attracted attention as an alternative to classical batch chemistry to ensure rapid and selective neutralization of such harmful chemicals with oxidizing agents. [16][17][18][19] Moreover, successful neutralisation by direct introduction of an aqueous solution of sodium hydroxide in the flow system has also been reported, 20 whereas a 3D-printed chemical generator of lithium ethanolate has been later reported as a reliable method. 21 Importantly, all these methods are not general and each focuses on a specific class of compounds: yperite, 16,17,19 V-series OPNAs, 21 sulfur-containing CWAs, 18 or Paraoxon.…”
