Hexavalent chromium Cr (VI) pollution is prevalent at decommissioned industrial sites and poses a serious risk to the surrounding ecosystem and human health. In this study, we presented a novel heavy metal-contaminated soil curing agent derived from industrial slag (slag and desulfurization gypsum) for the treatment and remediation of Cr (VI)-contaminated soil. This curing agent was used to treat Cr (VI)-contaminated soil at pollution control (78 mg/kg), light contamination (380 mg/kg), and heavy contamination (1000 mg/kg) levels. The migratory...
