REMEDIATION OF AS–CD CO-CONTAMINATED MINING SOIL BY ATTAPULGITE-SUPPORTED NANOSCALE ZERO-VALENT IRON: STABILIZATION PERFORMANCE, LEACHING RISK, AND PLANT RESPONSE
Attapulgite-supported nanoscale zero-valent iron (nZVI@ATP) was synthesized and applied as an in situ stabilization amendment for As–Cd co-contaminated mining soil. A 60-day incubation experiment combined with a ryegrass pot trial was conducted to evaluate changes in contaminant availability, leaching risk, operational...
