Problems solved by technology

[0008] The detection and identification of non-standard explosives is very important in criminal investigation. A slight deviation in the detection results of explosives will lead to misjudgment of the source and type of explosives, which seriously affects the normal detection of cases
However, the detection of materials such as caramel and other materials used in non-standard explosives has not been reported yet.

Embodiment 1

[0055] Utilize the test kit of the present invention to detect that water-soluble explosives are water-soluble explosive precursors and explosive residues:

[0056] Potassium permanganate detection

[0057] The aqueous solution of potassium permanganate is purple, use deionized water to dissolve the test substance to judge whether it contains potassium permanganate, first dissolve as much test substance as possible with reagent 1 (deionized water) 15mL, fully shake for 2min, Stand still; if the water phase of the liquid to be tested is colorless, it does not contain potassium permanganate, and then the nitrate, nitrite, chlorate, ammonium, urea, sugar, sodium The detection of ions or potassium ions, and the detection of nitrate, nitrite, chlorate, ammonium, urea, chloride, sulfide, sulfate, phosphate, sugar, sodium or potassium in water-soluble explosive residues detection;

[0058] If the solution is purple or light purple, then the analyte contains potassium permanganate. ...

Embodiment 2

[0060] Ammonium detection:

[0061]

[0062] Ammonium root can react in alkaline potassium iodomercurate to generate aminomercuric iodide, which is an orange-yellow precipitate. When detecting ammonium root, it is necessary to first carry out the detection of potassium permanganate according to Example 1;

[0063] Then select reagent 6 (potassium hydroxide 1-3mol / L, saturated potassium iomercurate at room temperature, solvent is deionized water), detect whether the liquid to be tested contains ammonium root, and slowly drop reagent 6 with a rubber dropper Add 1-2 drops to the solution to be tested, if orange precipitate appears in the solution to be tested, it means that the solution to be tested contains ammonium radicals; if there is no obvious phenomenon, the solution to be tested does not contain ammonium radicals.

Embodiment 3

[0065] Urea detection:

[0066]

[0067] Urea can react with p-dimethylaminobenzaldehyde to generate a kind of imine, and the product is dark yellow. When detecting urea, it is necessary to first detect potassium permanganate according to Example 1;

[0068] Then select reagent 7 (o-methylaminobenzaldehyde powder) to detect whether urea is contained in the liquid to be tested, take a spoonful of reagent 7 with a small medicine spoon, dissolve it in 2 mL of absolute ethanol, then add 2-3 drops of concentrated hydrochloric acid, and use glue Take 2-3 drops of the test solution from the tip dropper and slowly add it to the newly prepared test reagent. If the color of the solution turns yellow or gradually deepens, it means that urea exists in the test solution; if there is no obvious phenomenon, it means that the test solution does not contain urea. urea.

Abstract

The invention provides a kit for quickly detecting water-soluble explosives and a detecting method of the kit. The kit comprises 13 detection reagents; various cations, anions and molecular compounds in the water-soluble explosives and explosive residuals can be detected quickly and accurately by the kit; and the detection varieties include nitrate, nitrite, chlorate, ammonium, urea, permanganate, chloride ions, sulfur ions, sulfate, phosphate, sugar, sodium ions and potassium ions. The kit provided by the invention can be used for on-site explosive searching and quick determination of the nature of an explosive case, has the characteristics of simplicity, quickness, strong specificity, sensitive response, convenience in use and low cost, and can provide an effective technological means for the criminal investigation department of the public security system to solve explosive cases. The kit not only can be used for quickly detecting traditional explosives and explosive residuals, but also can be used for quickly and effectively detecting special explosives and explosive residuals in Xinjiang region.

Description

technical field [0001] The invention relates to a kit for rapidly detecting water-soluble explosives and a detection method thereof, in particular to the rapid detection of explosive precursors and explosive residues in water-soluble explosives. Background technique [0002] At present, terrorist activities are rampant in the world, and terrorist bombings are on the rise year by year, seriously threatening the safety of people's lives and properties. In recent years, terrorist activities in my country have also shown a significant growth trend, and bomb-related cases have occurred frequently. my country's control over standard explosives is relatively strict, while non-standard explosives have the characteristics of wide sources, easy acquisition, easy manufacture, and easy implementation, so they have become the most commonly used explosives by terrorists. General non-standard explosives are mainly composed of inorganic compounds, such as chlorate explosives, black powder,...
