- •
MgO decorated magnetic biochar was synthesized for phosphate recovery.
- •
The MgO decorated magnetic biochar could be separated easily by a magnet.
- •
The Qmax was around 121.25 mg P/g for biochar with Mg content around 20%.
- •
Phosphate sorption by MgO decorated magnetic biochar involved multi-mechanisms.
- •
Phosphate-loaded biochar improved plant growth and can be used as fertilizer.
