What is zero-valent iron powder?

.

Zero-valent iron powder is a material used in environmental remediation and water treatment. It consists of micron-scale iron powder particles that form zero-valent iron (Fe0) in water, which can effectively remove harmful substances from water.

.

The working principle of zero-valent iron powder

.

When zero-valent iron powder is added to water, Fe0 in the iron powder reacts with oxygen and water molecules in the water to produce hydrogen and iron hydroxide. These reactions cause a change in charge on the surface of Fe0, which makes it more active. At the same time, Fe0 can also chemically react with harmful substances in water, transforming them into harmless substances.

Application of zero-valent iron powder

.

Zero-valent iron powder can be applied in many aspects of environmental remediation and water treatment. It can be used for groundwater pollution remediation, soil heavy metal removal, removal of organic matter in water and so on. In addition, zero-valent iron powder can also be used to prepare other materials, such as zero-valent iron nanoparticles.

Advantages of zero-valent iron powder

.

Compared to other water treatment and environmental remediation methods, zero-valent iron powder has many advantages. First, it is a natural, non-toxic material that is safe to use. Secondly, it has the ability to efficiently remove harmful substances, which can quickly reduce the concentration of pollutants in the water. In addition, it has a lower cost and can be used as a cost-effective alternative.
