Thermal degradation of sulfur mustard (2,2′-dichlorodiethyl sulfide, HD) in the presence of metal oxide adsorbents was investigated by thermal desorption in conjunction with gas chromatography–mass spectrometry (GC-MS). Zr(OH)4, Al2O3, Al2CoO4, MgO, CeO2, and V2O5 were used as metal oxide adsorbents. Neat HD was spiked onto the metal oxides packed in glass tubes, which were kept at room temperature
图形摘要 摘要 通过热解吸结合气相色谱-质谱联用 (GC-MS) 研究了在金属氧化物吸附剂存在下硫芥(2,2'-二氯二乙基硫醚,HD)的热降解。Zr(OH)4、Al2O3、Al2CoO4、MgO、CeO2 和 V2O5 用作金属氧化物吸附剂。将纯净的 HD 加到装在玻璃管中的金属氧化物上,将其保持在室温下,然后通过热解吸系统在 100°C 的适度高温下加热。热降解产物直接通过GC-MS进行转移和分析。在 Zr(OH)4、Al2O3、Al2CoO4 和 CeO2 吸附剂存在下,HD 热降解的主要产物是 1,4-二噻烷和 1,4-氧杂噻吩。用 MgO 和 V2O5 没有观察到有效的降解。
