Removal of heavy metals from abandoned smelter contaminated soil with poly-phosphonic acid: Two-objective optimization based on washing efficiency and risk assessment

Yaxi Peng et al.

Summary: Soil washing is an effective technology for rapid remediation of contaminated sites, but the search for eco-friendly and cost-effective washing reagents continues. This study proposed a two-objective optimization method to investigate the removal efficiencies of eluents and risk of migration when soil Cd and Pb are washed by PPMP and BHMT. The research found that PPMP and BHMT have different mechanisms for removing Cd and Pb from the soil.
