Present study investigates the potential of CuO nanoparticles calcined at different temperature for the decontamination of persistent chemical warfare agent sulphur mustard (HD) at room temperature (30 ± 2 °C). Nanoparticles were synthesized by precipitation method and characterized by using SEM, EDAX, XRD, and Raman Spectroscopy. Synthesized nanoparticles were tested as destructive adsorbents for the degradation of HD. Reactions were monitored by GC-FID technique and the reaction products characterized by GC-MS. It was observed that the rate of degradation of HD decreases with the increase in calcination temperature and there is a change in the percentage of product of HD degradation. GC-MS data indicated that the elimination product increases with increase in calcination temperature whereas the hydrolysis product decreases.
本研究探讨了不同温度下煅烧的氧化铜纳米粒子在室温(30±2°C)下对持久性化学战剂芥子气(HD)的净化潜力。纳米粒子通过沉淀法合成,并通过 SEM、EDAX、XRD 和拉曼光谱进行了表征。合成的纳米粒子被测试为 HD 降解的破坏性吸附剂。通过 GC-FID 技术监测反应,并通过 GC-MS 对反应产物进行了表征。结果表明,HD 的降解速率随煅烧温度的升高而降低,HD 降解产物的比例也发生了变化。GC-MS 数据表明,随着煅烧温度的升高,消除产物的含量增加,而水解产物的含量减少。
