A REVIEW OF SOLIDIFICATION/STABILIZATION OF HEAVY METAL CONTAMINATED SOIL

Blog Article

Heavy metal contamination has occurred as a result of industrial civilization.Zinc, copper, chromium, and lead are Bouillon the most prevalent heavy metal pollutants.Heavy metal contamination has arisen as a significant environmental issue on a global scale.

Human and environmental health is at risk when soils are contaminated.as well as have poor engineering qualities.Solidification/Stabilization is a critical remediation strategy for polluted soils which is both efficient and cost-effective.

The solidification/stabilization approach has been frequently used to rehabilitate heavy metal-contaminated areas.First, The use of gypsum Electric Blanket to strengthen and leach polluted soils was reviewed.Also, cement/fly ash-solidified/stabilized soils have better engineering qualities.

On the other hand, the global output of phosphogypsum surpasses 300 million tons, raising disposal and environmental problems every year.The efficiency of the phosphogypsum-based stabilization/solidification technique was investigated, and the methods employed biochar and chemical agents such as citric acid and FeCl3.This review examines various remediation options as well as innovative soil amendments.
