A REVIEW OF SOLIDIFICATION/STABILIZATION OF HEAVY METAL CONTAMINATED SOIL

Heavy metal contamination has occurred as a result of industrial civilization. Zinc, copper, chromium, and lead are the most prevalent heavy pollutants. arisen significant environmental issue on global scale. Human health is at risk when soils contaminated. well have poor engineering qualities. Solidification/Stabilization critical remediation strategy for polluted which both efficient cost-effective. The solidification/stabilization approach been frequently used to rehabilitate metal-contaminated areas. First, use gypsum strengthen leach was reviewed. Also, cement/fly ash-solidified/stabilized better On other hand, output phosphogypsum surpasses 300 million tons, raising disposal problems every year. efficiency phosphogypsum-based stabilization/solidification technique investigated, methods employed biochar chemical agents such citric acid FeCl3. This review examines various options innovative soil amendments.
