文摘
- •
Five types of modified biochars were synthesized for phosphate remediation.
- •
The introduction of MgCl2 substantially increased surface area of biochar.
- •
MgCl2-alginate biochar microspheres had the highest phosphate sorption capacity.
- •
Phosphate sorption on biochars fits a pseudo second order and Langmuir model.
- •
Precipitation and ligand exchange were the possible sorption mechanisms.
