摘　　要：提出了一种综合分析鉴定含有疑似爆炸物的未知复杂多成分样品的方法:依托水分离方法分离样品组份,使不同组分分离到不同样品中,然后对各样品进行X射线衍射分析,对部分疑难样品进行扫描电镜、能谱仪等辅助手段分析。对江苏省某次刑侦案件送检样品进行鉴定,分析出其主要组份为硫磺、硝酸钾、高氯酸钾和铝粉等,含量分别为29.6%,26.7%,18.8%和9.7%等,最终确认样品为铝化炸药。该方法去除了样品的爆炸性,提高了鉴定准确度和定量精度,具有推广使用的价值。When identifying unknown multi-component complex samples containing suspected explosives, we could not adopt a targeted analytical test methods. A comprehensive analysis and identification method based on water separation method to release sample components, and then X-ray diffraction analysis on different components with scanning electron microscopy, energy dispersive spectroscopy and other auxiliary means of accurate identification was proposed. To identify a particular criminal investigation case in Jiangsu province inspection samples, the main components were estimated to be sulfur, potassium nitrate, potassium perchlorate and aluminum in an amount of 29. 6%, 26. 7%, 18.8% and 9. 7%, respectively. The final confirmation of the explosive sample was aluminum explosives. Explosions in the sample were removed, and the accuracy of the identification and quantification accuracy were improved.
