Iron powder deoxidizer is a commonly used chemical substance used to remove oxygen from water. The principle is as follows:
The main component of iron powder deoxidizer is fine iron powder (Fe) or iron alloy powder. In water, iron powder reacts with oxygen (O2) to form iron oxide (Fe2O3). This process is called a reduction reaction.
Example of reduction reaction:
2Fe+O2->2Fe2O3
In this reaction, iron powder acts as a reducing agent, reducing oxygen to iron oxide by releasing electrons to oxygen.
By adding sufficient iron powder deoxidizers to the water, oxygen in the water can be consumed. This is very useful for certain industrial processes or environments that require low oxygen conditions.
It should be noted that iron powder deoxidizers can only temporarily remove oxygen, as the generated iron oxide will exist in the water in the form of precipitation or suspension after the reaction is completed. In order to maintain the effectiveness of a low oxygen environment, it may be necessary to regularly add iron powder deoxidizers or take other measures.
In addition, the application of iron powder deoxidizers may be affected by water pH, temperature, and other water quality factors. In specific applications, product instructions and corresponding operating guidelines should be followed to ensure the safe and effective use of iron powder deoxidizers.
