Mini review on the application research of nanoscale zero valent iron in water treatment

Nanoscale zero valent iron (nZVI) is highly efficient in environmental pollution control technology, owing to its unique zero valent iron core iron oxide surface, which exhibits exceptional adsorption and reduction properties. This paper provides a comprehensive understanding of the physical and chemical properties of nano iron, with a primary focus on the preparation of nZVI. While nZVI finds extensive application in sewage treatment, it also demonstrates outstanding performance in the remediation of soil organic matter and heavy metal pollution, delivering excellent results and displaying good fluidity.
