Problems solved by technology

[0004] In order to solve the problems in the prior art, TKX-50 waste explosives and industrial wastewater containing TKX-50 explosives are often produced in the development of TKX-50. The current incineration method, oxidation method and other methods cannot treat TKX-50 in a green, safe and pollution-free manner. For the problem of disposal and destruction, the present invention provides a photochemical degradation treatment method for TKX-50 explosives. The present invention found that TKX-50 has higher photosensitivity, so the photodegradation pathway and method of TKX-50 were investigated. , and developed a new method of photochemical degradation of KTX-50 explosives, which can be used for environmental protection and green destruction of TKX-50 waste explosives

Embodiment 1

[0026] (1) Effect of different wavelengths of photolysis light sources on the degradation of TKX-50 explosives: Accurately weigh 11.80mg of TKX-50 in a 10mL colorimetric tube, add water to the mark, and prepare 5.0×10 -3 mol / L stock solution. Then take 100μL of the above stock solution in a 10mL colorimetric tube, add water to make it up to the mark, and prepare 5.0×10 -5 mol / L solution to be tested, the operation was repeated 5 times, and 6 solutions to be tested were prepared. Place the above-mentioned TKX-50 test solution under different light wavelengths such as sunlight, 365nm ultraviolet light, 254nm ultraviolet light, 365nm and 254nm composite ultraviolet light for 10 minutes, and use the TKX-50 test solution without any light as Blank control group, such as figure 1 shown. After 10 minutes, measure the maximum intensity of ultraviolet absorption of the TKX-50 solution to be tested by ultraviolet absorption spectrometer, and compare it with the sample without light t...

Abstract

The invention discloses a photochemical degradation treatment method of a TKX-50 explosive, and belongs to the technical field of energetic materials. The method specifically comprises the following steps: adding water into TKX-50 to prepare a TKX-50 solution, and then putting the prepared TKX-50 solution under an ultraviolet light source for illumination. Researches show that ultraviolet irradiation under a certain condition has a very good degradation effect on TKX-50, and a feasible technical route is provided for green destruction of TKX-50 explosives.

Description

technical field [0001] The invention belongs to the technical field of energetic materials, and relates to a safe disposal technology of TKX-50 waste explosives and an environmental protection treatment method of industrial wastewater containing TKX-50 explosives, in particular to a photochemical degradation treatment method of TKX-50 explosives. Background technique [0002] In recent years, it has been found that tetrazole energetic materials have many advantages such as high density, high enthalpy of formation, high gas production, low sensitivity, good thermal stability, and environmental protection of detonation products (mostly clean nitrogen), making The research and preparation of such explosives are highly valued. 5,5'-tetrazole-1,1'-dioxydihydroxyammonium (TKX-50), as a typical tetrazole energetic material, is a new type of explosive with high energy, low sensitivity and low toxicity. The energy level is comparable to CL-20, and the sensitivity is close to RDX. It...
