- •
Interaction between phosphate and AaN-RM was first time investigated.
- •
Phosphate adsorption was governed by heterogeneous processes.
- •
Different phosphate complexes were formed on AaN-RM surface.
- •
59.78% of phosphate was adsorbed by ion exchange and precipitation mechanisms.
- •
40.22% of phosphate was adsorbed by surface deposition mechanism.
