What is a deoxidizer

A deoxidizer is a chemical substance or device used to remove oxygen from the environment. They are typically used in industrial processes that require anaerobic or low oxygen conditions, laboratory research, and certain packaging and storage applications.

The following are several common deoxidizers:

Chemical deoxidizer: Chemical deoxidizer is a chemical substance that can react with oxygen and convert it into other substances. Common chemical deoxidizers include sulfites, sodium sulfide, iron powder, etc. These chemicals react when in contact with oxygen, thereby reducing the oxygen concentration in the environment.

Adsorbents: Some adsorbents can also be used as deoxidizers. For example, activated carbon can reduce the concentration of oxygen in the environment by adsorbing oxygen molecules.

Gas displacement device: The deoxygenation device can also physically expel oxygen from the space. These devices typically use inert gases such as nitrogen or argon for displacement, thereby reducing the concentration of oxygen.

The use of deoxidizers depends on the application requirements. In the industrial field, deoxidizers are commonly used to prevent oxidation corrosion, protect the sterilization process, and improve storage conditions. In laboratory research, deoxidizers can be used to create reaction environments under anaerobic conditions.

It should be noted that the use of deoxidizers should follow corresponding safety operating procedures, and appropriate deoxidizers and their usage methods should be selected according to the specific situation.
