建立了用消毒液ＤＳ２对含磷毒剂沙林（ＧＢ）和梭曼（ＧＤ）消毒后的样品处理与制备的方法，使用气相色谱－质谱法对消毒后产物进行了分析与鉴定。对ＤＳ２消毒ＧＢ和ＧＤ反应的机理作了探讨。 The method of treating and preparing samples with sterilizing liquid DS2 for sterilizing Sarin (GB) and soman (GD) was established. The products after disinfection were analyzed and identified by gas chromatography-mass spectrometry. The mechanism of DS2 disinfection of GB and GD was discussed.
