文摘
- •
Hydrous zirconia–coated magnetite was used for phosphate capture.
- •
Regulation of pH was able to enhance P removal in the presence of coexisting ions.
- •
Phosphate was coordinated onto zirconium by replacement of hydroxyl groups.
- •
The material could be easily separated from water for reuse by a magnet.
- •
Desorption of phosphate from the material could be achieved with NaOH treatment.
