Analysis of Explosion Products with Ion Chromatography and GC-MS
摘 要
用离子色谱和热解吸-气相色谱-质谱法测定炸药的爆炸产物.爆炸产物中的氰化物用0.1 mol·L-1氢氧化钠溶液吸收后,用离子色谱法检测,检出限(3S/N)为0.01 μg·L-1,回收率为92.6%,相关系数为0.999 8,测定结果的相对标准偏差为3.8%.爆炸产物的主成分和微量成分直接进样,用热解吸-气相色谱-质谱联用法分析,检测了联苯、1-甲基-(1H)-吡喏-2-乙腈、5-氨基-3,4-二氢-(2H)-吡喏-2-乙腈、硝基苯、苯等有毒产物.
Abstract
Methods of ion chromatography and GC-MS were proposed for the determination of the explosion products of explosives and reported in this paper.The cyanide in gaseous products was absorbed with 0.1 mol·L-1 NaOH solution and determined by ion chromatography (IC),with detection limit of 0.01 μg·L-1,recovery of 92.6%,correlation coefficient of 0.999 8 and RSD of 3.8%.The major and micro amount of components of the explosion products were analyzed by thermal desorption-GC-MS with direct sample introduction.Biphenyl,1-methyl-hydro-(1H)-2-acetonitrile,5-amino-3,4-dihydro-(2H)-pyrrole-2-acetonitrile,nitro-benzene,benzene and other toxic compounds were detected.
