燃烧型发烟剂烟幕成分分析

Component analysis of smokescreen combusting from a smoke agent

通过独立并行的三通道采样分析方法,借助实时傅里叶红外光谱、电感耦合等离子体质谱、阴离子色谱、气相色谱-质谱等检测手段,对某燃烧型军用发烟剂烟幕的主要成分进行定性和定量分析。测试结果表明,烟幕中的无机气体主要成分为一氧化碳,挥发性有机物主要成分为六氯乙烷、四氯乙烯、四氯化碳和六氯丁二烯,固体颗粒物中无机阴离子主要成分为Cl–,金属元素主要成分为Zn和Al。该方法对多组分气溶胶体系实现系统全面的成分分析,具备一定的普适性,也可用于燃烧型以外的烟幕成分分析,对军用发烟剂的研制和安全性评估具有参考价值。

A detection method is introduced,which utilizes three independent channels to sample the components of smokescreen combusting from a smoke agent seperately.In this method,four analytical chemical measures are performed to fulfill the composition analysis,including Fourier transform infrared spectrometer(FTIR),inductively coupled plasma mass spectrometry(ICP-MS),ion chromatography(IC),gas chromatography-mass spectrometry(GC-MS).As results,the main inorganic gas of the smokescreen is carbon monoxide,while the main volatile organic compounds(VOCs)are hexachloroethane,tetrachloroethylene,carbon tetrachloride and hexachloro-1,3-butadiene.In the solid particles collected from the smokescreen,the main inorganic ion is Cl–,and the main metal elements are Zn and Al.This method accomplishes the analysis of nearly all the composition in the aerosol,which is quite inspiring for the research and safety assessment of military smoke agent in the future.
