TATP模拟物的设计及安全性评估

Design and Safety Evaluation of TATP Simulant

三过氧化三丙酮(TATP)直接用于安检培训具有危险性高、安全隐患多的问题。设计出可代替TATP在X光机、CT机等高通量安检仪中成像的模拟物。物质组成为m(葡萄糖)m(十六醇)m(蔗糖)=25.779.6814.55,与TATP具有相似的外观及有效原子序数,元素质量分数相差小于0.020%,堆积密度相差0.012 g/cm^3。为确保模拟物在红外、拉曼等高灵敏性安检仪中亦存在特征信号,在混合物中加入适量TATP。结果表明,当TATP的加入量为20%(质量分数)时,可有效地表征出混合物中TATP的红外、拉曼特征峰;同时,体系相容性较好,机械感度低,且不具有爆炸性。优化后的配方为:m(葡萄糖)m(十六醇)m(蔗糖)m(TATP)=20.627.7411.6410.00。该模拟物与TATP的相似度高、安全性好,可直接用于安检人员培训。

Aiming at the problem that triacetone trisperoxide(TATP)has high risks and many potential safety ha-zards when it is directly used for security inspection training,a simulant was designed to replace TATP for imaging in high-throughput security check equipment such as X-ray machines and CT machines.In TATP simulant system,m(glucose)m(cetyl alcohol)m(sucrose)=25.779.6814.55.It has the similar appearance and effective atomic number to TATP,the difference in chemical element percentage is less than 0.020%,and the difference in bulk density is 0.012 g/cm^3.In order to ensure that the simulant also has characteristic signals in high-sensitivity security inspection instruments such as infrared and Raman,an appropriate amount of TATP was added to the mixture.Results show that when the addition of TATP reaches 20%(mass fraction),infrared and Raman characteristic peaks of TATP in the mixture can be effectively characterized.Meanwhile,the system has good compatibility and low mechanical sensitivity,and it is not explosive.The optimized simulant formula is m(glucose)m(cetanol)m(sucrose)m(TATP)=20.627.7411.6410.00.It has the advantages of high similarity and good safety and can be directly used for security inspection personnel training.
