摘　　要：采用脉冲电晕放电产生的等离子体对沙林毒剂的模拟剂甲基磷酸二甲酯进行消除研究。着重进行了脉冲峰压、脉冲频率、初始质量浓度、气体流量等对消除率的影响实验。结果发现,消除率随脉冲峰压和脉冲频率的增加而提高,随气体流量和初始质量浓度的增大而降低。同时发现产物中含有CO2、H2O、丙酸、甲基磷酸甲酯和磷酸(或P2O5)等物质。The present paper aims to introduce the authors＇ experiment on treating toxic organic exhaust gases by using the pulsed corona discharge plasma, which is said to be a new promising technology in treating toxic gas, The authors＇ studies indicate that plasma technology can effectively decontaminate the toxicant and chemical agents. Dimethyl methyl phosphomate（DMMP）, a stimulant agent of sarin as well as the raw material of sarin, has been treated by a wirecylinder pulsed corona discharge plasma reactor, which is controlled by a positive pulsed corona discharge power supply. The factors influencing the remoral efficiency has also been discussed in this article, such as pulse peak voltage, pulse frequency, initial concentration and gas flux. The results show that the removal efficiency of DMMP increases as the rising of pulse peak voltage, pulse frequency, while decreasing with the rising of gas inlet concentration and flux. The greatest removal efficiency of DMMP proves that the efficiency can be as high as 95.4% by means of GC quantitative analysis of DMMP. Qualitative analysis clone by using GC-MS and Ion Chromatograph （IC）. CO2, H2O and propionic acid are found in the outlet gas, while phosphoric acid （or phosphorus（ V ） oxide） and methyl phosphomate have also been found on the surface of the discharge electrode.
