In the process of redox treatment; in the process of biological treatment of sewage, it can be used as a nitrogen source in microbial nutrients, etc.

Dilute nitric acid is an important basic chemical raw material with a molecular formula of HNO3 and a molecular weight of 63.01. It is a colorless or light yellow transparent liquid. In recent years, the market consumption structure of dilute nitric acid products in my country has changed greatly. It is mainly used in the chemical industry, metallurgical industry, and medicine. , military, chemical cleaning and nitro compound fertilizer and other fields.


Functional application of dilute nitric acid:

1. As an important chemical raw material, dilute nitric acid is mainly used to manufacture compound fertilizers such as nitrophosphate fertilizer and nitrogen, phosphorus and potassium; it is used in the organic industry to manufacture nitrohexane, l-nitropropane, and other nitro compounds; it is used in the dye industry to treat The synthesis of dye intermediates such as dyes; the paint industry is used to manufacture nitro varnish and nitro enamel; dilute nitric acid is used as an oxidant to oxidize alcohols and other chemicals, and has been used in rocket propellants; dilute nitric acid is also used to manufacture calcium, copper, and silver , cobalt and strontium nitrate raw materials.

2. In the process of biological sewage treatment, dilute nitric acid can be used as nitrogen source in microbial nutrients, etc. In addition, dilute nitric acid is widely used in the manufacture of chemical fertilizers, chemical fibers, medicines, dyes, rubber, etc. In the national defense industry, metallurgical industry, printing and dyeing industry and other industrial sectors, it is also an indispensable and important analytical chemical reagent.

3. Dilute nitric acid is used as etchant and strong acid cleaning etchant, and can be used in conjunction with hydrogen peroxide.

4. Dilute nitric acid is used as an analytical reagent, such as a solvent, an oxidizing agent, and also used in organic synthesis to prepare various nitro compounds.

5. Dilute nitric acid is one of the important basic chemical raw materials and a chemical product with a wide range of uses. In the field of water treatment, dilute nitric acid can be used as a cleaning and derusting agent for carbon steel and stainless steel equipment, and in the process of redox treatment of sewage and wastewater; in the process of biological treatment of sewage, it can be used as a Nitrogen source etc.
