Microwave-assisted pyrolysis of dyeing sludge: Reaction kinetics, elemental transformation, and heavy metal migration

Key Points

• Heavy metal migration occurs during microwave-assisted pyrolysis of dyeing sludge, impacting environmental safety.
• Key findings show an increase in mobility of heavy metals like chromium and lead compared to traditional methods.
• Assessment using reaction kinetics reveals significant elemental transformations under controlled conditions and low energy use.
• Findings highlight environmental concerns associated with dyeing sludge treatment, necessitating further analysis in real-world settings.
