Abstract

The invention relates to an identification detection method for nitro-aromatic explosives. Sensing thin films of the same fluorescent unit connected through different connecting arms have different quenching responses to nitro-aromatic compounds, and six fluorescent sensing thin films modified by 5-dimethyl amino-1-naphthalene sulfonyl taking different diamines as connecting arms are used for further analyzing quenching response results by using a weighted principal component analysis method to learn about that four standard nitro-aromatic explosives 4,6-trinitrotoluene, 2,4,6-trinitrophenol, 2,4-dinitrotoluene and nitrobenzene are in different areas in coordinates to further fulfill the aim of identifying the four nitro-aromatic explosives in an explosive and make the identification detection of the four nitro-aromatic explosives in the explosive possible. According to the identification detection method, the nitro-aromatic compounds can be well responded and sensitively detected.

Description

technical field

[0001] The invention belongs to the technical field of detection of nitroaromatic explosives, in particular to a method capable of identifying nitroaromatic explosives in explosives. Background technique

[0002] In recent years, with the increasing demand for terrorist threats, the application of chemical and biological weapons in warfare, non-metal mine detection, and environmental quality monitoring, countries around the world have paid more and more attention to the research of various high-performance thin-film sensors. At present, the trace detection techniques for p-nitroaromatic explosives are mainly various spectroscopic methods and chemical sensing methods. Spectroscopy mainly includes chromatography, mass spectrometry, Raman spectroscopy, and ion mobility; chemical sensing mainly includes electrochemical sensing, mass sensing, and fluorescence sensing. Compared with other methods, the fluorescent thin film sensor has the advantages of high sensiti...
