Description

technical field

[0001] The invention relates to the field of explosive detection, in particular to a detection method for p-trinitrotoluene by means of fluorescence sensing. Background technique

[0002] 2,4,6-Trinitrotoluene (TNT) is white or amaranth light yellow needle crystal, odorless and hygroscopic. The compound is a relatively safe explosive, resistant to impact and friction, but sudden heating of any amount can cause an explosion. The compound has moderate toxicity and can penetrate through the skin, respiratory tract and digestive tract. Its main hazard is chronic poisoning. The compound can irritate the skin locally to produce dermatitis and yellowing. The chronic effects are mainly manifested as toxic gastritis, toxic hepatitis, aplastic anemia, anemia, and toxic cataract.

[0003] Due to the low cost of raw materials for TNT preparation of explosives, and the advantages of saving time and labor in construction operations (such as blasting of abandoned buildi...
