Spectroscopic analysis of the interaction mechanism between manganese( ii ) and microbial extracellular polymeric substances in landfill leachate treatment

Key Points

• The research investigates how manganese(ii) interacts with microbial extracellular polymeric substances during landfill leachate treatment.
• Conducted spectroscopic analysis of manganese(ii) and extracellular polymeric substances
• Evaluated COD removal efficiency
• Assessed sludge settleability using altered proteins
• Low manganese(ii) levels improved COD removal in leachate
• TB-EPS showed stronger interaction with manganese(ii)
• Altered proteins enhanced sludge settleability
