摘　　要：用X射线荧光能谱法检测了含十二烷基苯磺酸铈(CDBS)和硬脂酸铈(CSA)的硝铵(AN)炸药(ANE)。根据含CDBS和CSA的AN炸药的典型X射线荧光能谱,提出了用稀土(XT)的Kα1峰的逃逸峰作为检测AN炸药的特征峰,其值为6.11 keV。考察了该逃逸峰的信号强度(Is)与炸药中XT含量(x%)、探测距离(L)、探测时间(t)、炸药量(m)的关系,并列出相应的关系式,认为在XT含量不低于0.2%,检测时间不少于5 s,AN炸药量不少于50 g的情况下,该检测技术适合检测AN炸药。Cerium dodecyl benzene sulfonate （CDBS） or cerium stearate （CSA） was proposed to be used as tracing additives of ammonium nitrate explosives （ANE）. Based on the typical X-ray fluorescence spectrum of the CDBS or CSA containing ANE, XRF tracing detection of the explosive was performed by detecting the escape peak of the characteristic Kα1 peak of rare earth element. Energy of the escape peak was found to be 6. 11 keV. Relationships between the intensity of the escape peak （Is） and the content of rare earth element and the distance of detection （L）, and the time of detection （t）, and the amount of explosive （m） were studied and formulated. It was concluded that the proposed method is suitable to be used for the XRF tracing detection of ANE under the following conditions; ① content of rare earth element （w）≥0. 2% ; ② time of detection, t≥5 s;③ amount of ANE m≥50 g.
