微痕量炸药的准确、快速检测对反恐、非金属地雷探测、环境质量监测等都具有十分重要的意义。在概括现有炸药检测技术的基础上,着重介绍用于微痕量硝基芳烃类炸药检测的均相荧光传感器、薄膜荧光传感器和光纤荧光传感器,其中,薄膜荧光传感器因其灵敏度高、选择性好、可重复使用和易于器件化等优点将在微痕量硝基芳烃类炸药的检测中获得实际应用。
The fast and accurate detection of trace explosives has become increasingly important in terms of antiterrorism, nonmetal landmine detection and environmental monitoring. On the bases of brief introduction of general techniques for the detection of explosives, various fluorescence sensors for the detection of trace amount of nitroaromatic explosives, film sensors and fiber optic sensors are addressed. The fluorescence film sensors will find practical uses in the detection of trace amount of nitro-aromatic compounds explosives because of their high sensitivity, high selectivity, and also because they are re-usable, and they are easy to be made into devices.
