Problems solved by technology

However, Fenton's reagent's ability to oxidize organic matter and oxidation efficiency are affected by many conditions, such as pH value, Fe 2+ / H 2 o 2 Proportion, reaction temperature, etc., the control conditions are more complicated when actually processing isopropyl nitrate

Embodiment 1-16

[0018] Prepare 150mL sodium sulfide solutions of different concentrations, add them to a constant temperature water bath, raise the temperature to the corresponding temperature, then adjust the pH value, add 5mL isopropyl nitrate, and start the reaction. Take 10 mL of the reaction product at 25 min, 50 min, 75 min, and 8 h of reaction, extract with 10 mL of diethyl ether, analyze the extraction phase by gas chromatography, and calculate the removal rate of isopropyl nitrate.

[0019] The concentration of sodium sulfide solution, reaction temperature, reaction pH value and removal rate of isopropyl nitrate in each embodiment are shown in Table 1 below.

[0020]

[0021] According to the analysis of the relevant factors of Examples 1-16, the primary and secondary order of the influence of each factor on the reaction efficiency is sodium sulfide concentration, pH value, and temperature. Compared with treating isopropyl nitrate with Fenton's reagent, the method of the inventi...

Abstract

The invention relates to the technical field of nitrate ester energy material safety processing, in particular to the technical field of treatment of wastewater containing energy materials, and particularly discloses a safe and efficient processing method of iso-propyl nitrate. The method includes the following steps that iso-propyl nitrate or an aqueous solution of iso-propyl nitrate is added into an excessive sodium sulfide aqueous solution with the concentration of 0.1-0.2 mol / L for reaction, the pH of the reaction solution is controlled to be 6-14, and the temperature is controlled to be 50-70 DEG C. By means of the method, iso-propyl nitrate and the aqueous solution of iso-propyl nitrate can be efficiently and safely processed so as to be decomposed, and the method has the advantages of being high in processing ability, high in efficiency and removal rate, easy to operate, and easy to implement.

Description

technical field [0001] The invention relates to the technical field of safe treatment of nitrate ester energetic materials, in particular to the technical field of wastewater treatment containing such materials. Background technique [0002] Isopropyl nitrate is a nitrate ester energetic material with low sensitivity, and it will cause combustion and explosion when exposed to open flame or high heat. Isopropyl nitrate is slightly soluble in water, has strong volatility and toxicity, and is harmful to human body after inhalation, oral administration or skin absorption. The wastewater discharged from factories producing and using isopropyl nitrate contains a certain amount of isopropyl nitrate, so the wastewater containing isopropyl nitrate must be treated to decompose the isopropyl nitrate therein. [0003] Different from ordinary esters, isopropyl nitrate is highly oxidizing and is a flammable and explosive energetic material. If the wastewater containing isopropyl nitrate ...
