文摘
- •
A combined biofilm-biochar approach for contaminant removal was evaluated.
- •
Biotic-biochar was more effective at removing naphthenic acids vs. sterile biochar.
- •
Evidence for enhanced organics removal by biotic-biochar in the presence of metals.
- •
Greater metal sorption evident with biofilm-attached biochar.
- •
This combined approach was more effective at removal than either independently.
