Research Progress on Nanoscale Zero Valent Iron Remediation of Heavy Metal Contaminated Soil

With the acceleration of industrialization, the problem of heavy metal pollution in soil is becoming more and more serious, posing a threat to the ecological environment and human health. As an emerging remediation technology, nano-ZVI has shown great potential in the field of remediation of soil heavy metal pollution due to its efficient reduction ability and large specific surface area. In this paper, the research progress of nano-ZVI remediation of heavy metal contaminated soil is reviewed, including the preparation method and modification method of nano-ZVI and its application in the remediation of heavy metal contaminated soil, aiming to provide scientific basis and technical support for the treatment of soil heavy metal pollution.
