摘要
采用板-板式介质阻挡放电反应器对芥子气的模拟剂2-氯乙基乙基硫醚（2-Chloroethyl ethyl sulfide，2-CEES）进行洗消实验研究，并探讨了放电功率和气体流量对洗消率的影响．研究发现，在放电功率70W、气体流量75L·h^-1的条件下对初始浓度0～280mg·m^-3的染毒空气洗消效果较好．因此，在该条件下，对芥子气染毒空气进行深入洗消研究．结果表明，当初始浓度低于150．2mg·m^-3时洗消后尾气的残余浓度低于安全允许浓度（0．0083mg·m^-3）．同时，采用GC-MS和离子色谱对洗消产物进行分析，发现介质阻挡放电等离子体将芥子气分解成H2O、CO2、SO3、HCl、芥子砜（C1CH2CH2SO2CH2CH2Cl）和芥子亚砜（C1CH2CH2SOCH2CH2Cl）等．
A plate-plate dielectric barrier discharge reactor was used to decontaminate 2-Chloroethyl ethyl sulfide （2-CEES）, a surrogate of mustard. The effect of discharge power and gas flow on the decontamination efficiency of 2-CEES was studied, and the maximal decontamination efficiency could be achieved under the condition of 70W of discharge power and 75L·h^-1 of gas flow, with the initial concentration varied from 0 to 280mg·m^-3. Then the decontamination experiment for mustard was carried out at this more optimal condition. The results indicated that mustard in air with an initial concentration of less than 150. 2mg· m^-3 could be decontaminated to lower than 0. 0083 mg·m^-3, the permissible safety concentration. The decontamination products were H2O, CO2 , HCl, SO3 , bis（2-chloroethyl） sulphone and bis（2-chloroethyl） sulphoxide which were analyzed by GC-MS and ion chromatograph.
