摘 要: | 以马拉硫磷为毒剂模拟剂,采用脉冲电晕放电等离子体对其染毒空气进行洗消实验研究,考察了脉冲电压、脉冲频率和气体流量对洗消效果的影响。结果发现洗消率随着峰值电压和脉冲频率的增大而提高,随着气体流量的增大而减小。对不同浓度马拉硫磷的降解结果表明,随着初始浓度的增大洗消率降低,但绝对消除量增加。采用了GC-MS和化学方法对洗消产物进行定性分析.

Abstract: | Decontamination of malathin, a surrogate of chemical agnet, is carried out by pulsed corona discharge plasma. The effects of peak voltage, pulse frequency and gas flow rate on the decontamination efficiency are investigated. Result shows that the decontamination efficiency is increased with the rising of pulse peak voltage and pulse frequency, but decreased with the rising of gas flow rate. The decontamination results for different concentration of malathin indicates that the decontamination efficiency is decreased as the rising of initial concentration, while the absolute decontamination quantity increased at the same time. The decontamination products are qualitatively analyzed by GC-MS and chemical methods. |
