摘    要:采用冷阱预浓缩-气相色谱/质谱联用法测定环境空气中硫化氢、甲硫醇、甲硫醚、二硫化碳、二甲二硫、噻吩等6种硫化物,讨论了采样容器材质的影响。方法线性良好,6种硫化物的检出限为1.0μg/m3~5.0μg/m3,混合标准气平行测定的RSD≤8.1%,加标回收率为93.5%~97.3%。

关 键 词:硫化物  气相色谱/质谱联用法  环境空气

Abstract:Sulfureted hydrogen,methanthiol,dimethyl sulfide,carbon disulfide,dimethyl disulfide and thiofuran in ambient air were determined by GC/MS with a trap concentrator.The influence of materials about sampling containers was discussed.Results showed good linearity of method was obtained.Detection limits of 6 kinds of sulfides were between 1.0 μg/m^3 and 5.0 μg/m^3.RSD of parallel samples of mixed standard gases was≤8.1%.Spiked recoveries of samples were between 93.5% and 97.3%.
Keywords:Sulfide  GC/MS  Ambient air
