High-efficiency decomposition technology for volatile chemical warfare agent sarin was developed using a dielectric-barrier discharge (DBD). The power consumptions of the developed device for which the gap lengths of the plasma-generation sites were 1.0–2.0 mm, were found to be 22–27 W, respectively. The DBD driven sarin-decomposition amount per unit time and the decomposition efficiency in the optimized condition were obtained to be 2.05 × 10 −3 mg/s and 1.38 × 10 −4 mg/W, respectively, measured by ion mobility spectrometer. Sarin-decomposition products were investigated using a gas chromatography–mass spectrometry with tert -butyldimethylsilylation derivatization, indicating that isopropyl methylphosphoric acid (IMPA), methylphosphoric acid (MPA), and phosphoric acid (PA) were generated during sarin decomposition by DBD. The decomposition efficiency at 37 W decreased by 41% molar concentration compared with that at 15 W, but the production levels of IMPA, MPA and PA were changed from 10.0%, 41.5% and 3.9% to 7.2%, 21.3% and 6.4%, respectively.

电介质阻挡放电法开发挥发性化学战剂沙林高效分解技术

使用介质阻挡放电（DBD）开发了挥发性化学战剂沙林的高效分解技术。所开发的设备的功率消耗，其等离子体产生位置的间隙长度为 1.0-2.0 毫米，分别为 22-27 W。通过离子迁移谱仪测得DBD驱动的单位时间沙林分解量和优化条件下的分解效率分别为2.05×10 -3 mg/s和1.38×10 -4 mg/W。使用带有叔丁基二甲基甲硅烷基化衍生化的气相色谱-质谱法研究沙林分解产物，表明在 DBD 分解沙林过程中产生了异丙基甲基磷酸 (IMPA)、甲基磷酸 (MPA) 和磷酸 (PA)。
