Study on the mechanisms of heavy metal immobilization and migration in the plasma co-melting process of iron-rich hazardous waste fly ash and bottom ash.
Hazardous fly ash (HFA) contains large amounts of toxic heavy metals and poses significant potential risks to the environment. In this study, HFA was co-melted with hazardous bottom ash (HBA) and waste glass (WG) in a plasma system to investigate its vitrification behavior, heavy metal migration, and solidification mec...
