Migration behaviour of heavy metals and vitrification characteristics in melting of municipal solid waste incineration fly ash

Key Points

• Vitrification alters the migration behaviour of heavy metals, affecting their stability.
• The study finds that varying heating rates impact the leaching of metals from fly ash.
• Assessment of municipal solid waste incineration fly ash shows diverse chemical characteristics influencing metal migration.
• Implications for waste management highlight the need for careful monitoring of heavy metals during disposal.
