Description
The technical field is as follows: the invention relates to a non-contact peroxide explosive detection device based on a chemical fluorescence principle.
Background
In recent years, as the application range of energetic materials is continuously expanded, the unexpected safety problem is still serious, and the safety of people's lives and properties is seriously threatened. At present, the problems of safe production, safe storage, safe transportation, safe use, safe management and the like of explosives have attracted extensive attention in many countries of the world. The national border of China is long, the population is large, the transportation hub is developed, and the method is also an imported and exported country of world trade, hidden explosives are timely and effectively detected to be urgently needed, which has important significance on the safety of China and international society, so that the explosive detection technology is widely applied to departments such as customs, aviation, subways, stations and the like. Peroxide explosives are novel explosives which contain more than one peroxy group R-O-O-R in a molecular structure and are in a ring structure, typical representatives of the peroxides are tripropionone tripropoxide TATP and hexamethylene-triamine-diperoxide HMTD, the molecular structure of the peroxides does not contain chromophore and nitro group, solid residues are few after explosion, the peroxides are easy to sublimate and volatilize at normal temperature, and the like, and the detection difficulty is high. Therefore, the research on a small peroxide explosive detection device with high sensitivity and low detection limit is of great significance.
At present, methods for detecting explosives include a macro detection method and a trace detection method. The macro detection method is used for detecting the overall appearance of the explosive, has the defects of low sensitivity, high price, large equipment volume and the like, and has limitation in application. Trace detection is a technique that detects trace amounts of explosives remaining on the surfaces of containers that contain and adhere to vapors emitted by explosives, as well as on the surfaces of any exposed explosive objects, including human bodies. At present, methods for detecting trace explosives mainly include a spectrometry method, a mass spectrometry method, a terahertz spectrometry method, a fluorescence detection method, a biosensing technology and the like. Mass Spectrometry (MS) is an effective tool for detecting explosives, and is often combined with chromatography for analytical detection, most commonly gas chromatography-mass spectrometry (GCMS) and high performance liquid chromatography-mass spectrometry (HPLC-MS), but mass spectrometry has high cost, requires pretreatment of a sample, requires a long time for analytical detection, requires a pure sample, and is bulky. The safety of the ion mobility spectrometry detection needs to be improved, and the detected explosive has the explosion risk. The chemofluorescence sensor detection method has the advantages of high sensitivity, good selectivity, less required sample amount, simple method and the like, and is very suitable for trace non-contact detection.
The phenylboronate compound is proved to react with hydrogen peroxide vapor specifically, and generates obvious fluorescence enhancement effect Xu M, Han J M, Wang C, et al. Therefore, the hydrogen peroxide vapor can be detected by the change of the emission intensity of a specific wavelength before and after the reaction, and the detection limit is reported to be lower than 5ppb as a detection substance for detecting the hydrogen peroxide vapor in a trace non-contact manner.
If a plurality of explosives are to be detected, different types of detection substances are synthesized to be correspondingly detected, the fluorescence emission spectrum peaks of different fluorescence detection substances are often in different wave bands, and light except the fluorescence emission spectrum peak needs to be filtered to obtain a high-sensitivity fluorescence signal, which causes great difficulty; the synthesis of the detection substance is generally complicated, the properties such as the service life and the like of the detection substance are different, and the large-scale practical application is difficult. In addition, the trace detection methods are usually contact-type, that is, the residual chemical components on the detected object are collected, for example, the detection substance is placed in a cuvette to be detected by a solution, or the detected object is wiped to determine whether the detected object carries or contacts the explosive, and these methods are very limited, and have complex detection process, low sensitivity, inconvenient carrying, sometimes unable to provide accurate detection information, too long detection time and the like.
The phenylboronate compounds are insensitive to peroxide explosive vapors due to their specific reaction to fluorescently detect the substance. The invention provides a non-contact peroxide explosive detection device based on a chemical fluorescence principle, which is provided with a peroxide explosive gas enrichment and conversion bin, wherein the enrichment and conversion bin can achieve the purpose of enriching and converting different explosive gases to be detected by additionally arranging different catalyst modules or light and heat decomposition modules; the explosive gas with trace peroxide is decomposed by an enrichment conversion bin to obtain a product H2O2The air enters the air passage to react with the test paper of the detection substance specifically to generate chemical fluorescence, the chemical fluorescence is detected by the detection module, and a detection curve is displayed on a computer in real time, so that the non-contact detection of the peroxide explosive is realized.
