Basic Information
Definition: Ozone is an allotrope of oxygen with the chemical formula O₃, a pale blue gas with a fishy odor.
Chemical Properties:
Strong oxidizing property: It is a stronger oxidant than oxygen and can undergo oxidation reactions at lower temperatures.
Non-flammable, pure substance
Physical Properties:
Under normal temperature and pressure, it has poor stability and can decompose spontaneously into oxygen.
Has the smell of grass
Liquid: dark black; solid: blue-black
Distribution:
Mainly distributed in the stratosphere at altitudes of 10 to 50 km, with a maximum between 20 and 30 km , .
Generated by the absorption of sunlight with wavelengths less than 185 nm by oxygen in the atmosphere.
Impact on the human body:
Inhaling a small amount is beneficial to the body.
Inhaling excessive amounts can be harmful to human health.
May cause respiratory tract irritation symptoms, coughing, headache, and chest discomfort.
Application:
Disinfection and Sterilization: Capable of swiftly and thoroughly eliminating viruses and bacteria in air and water.
Bleaching: As a strong oxidizing agent, it can be used as a bleaching agent.
Deodorization: Utilizes its strong oxidative decomposition ability to eliminate odors from air and water.
Treating diseases: There are various applications in the medical field, such as treating lumbar disc herniation, viral hepatitis, ischemic hypotaxis diseases, etc.
Generation Method:
Ultraviolet irradiation method: Using ultraviolet light to irradiate dried oxygen
Electrolysis: Using low-voltage direct current to electrolysis water.
Agrochemical Method: Utilizing various radioactive sources to dissociate oxygen molecules through nuclear radiation.
Medium-blocking discharge method: Produces corona in a gas through an alternating high-voltage electric field.
Ozone Layer:
The most concentrated part is located at an altitude of 20-25 kilometers.
The ozone layer absorbs ultraviolet rays, which has a warming effect on the atmosphere, and also protects Earth's organisms from short-wave ultraviolet radiation.
Safety Precautions
High concentrations of ozone are harmful to the human body.
Exposure to ozone may cause respiratory inflammation and damage the cilia of the epithelium in the terminal bronchi oles.
Long-term exposure to a certain concentration of ozone is also prone to secondary upper respiratory tract infections.
After using ozone disinfection, please ensure proper ventilation.
