Phosphate removal from water using freshly formed Fe-Mn binary oxide: Adsorption behaviors and mechanisms

- A freshly formed Fe-Mn binary oxide (FMBO) suspension was synthesized.
- FMBO had different physicochemical properties from the mixture of Fe and Mn oxides.
- Phosphate adsorption followed trend FMBO > mixed oxide > ferric oxide at pH 3-10.
- The mechanism of phosphate adsorption on FMBO was clarified.
