摘　　要：基于紫外分光光度法和气相色谱法缺乏对膨化硝铵炸药爆炸物特性分析导致残留物回收率和检测完整度差,采用高效液相色谱检测方法检测爆炸时土壤中污染物的残留物。通过标样与未知样品组分色谱保留时间识别炸药爆炸后成分。分析炸药成分液相色谱图,确定易燃物质硝酸铵、硝基化合物硝酸铵、含金属粉末硝酸盐、硝酸脲铵油污染残留物。实验得出结论,该方法回收率达90%左右,残留物完整度检测为100%,为保护土壤免受炸药残留物侵蚀提供保障。Due to the lack of analysis on the characteristics of explosives of expanded ammonium nitrate explosive by ultraviolet spectrophotometry and gas chromatography,the recovery rate and detection integrity of residues are poor.High performance liquid chromatography(HPLC)detection method is used to detect the residues of pollutants in soil during explosion.The composition of explosive was identified by retention time of standard sample and unknown sample.The liquid chromatogram of explosive composition was analyzed to determine the residues of flammable substances such as ammonium nitrate,nitro compound ammonium nitrate,nitrate containing metal powder and ammonium urea nitrate oil.The experimental results show that the recovery rate of this method is about 90%,and the detection of residue integrity is 100%,which provides guarantee for protecting soil from the erosion of explosive residues.
