- •
D2EHPA a magnetic adsorbent was used for the adsorption of Mo (IV).
- •
The Qmax of Mo (IV) was achieved at 0.5 M HNO3 concentration.
- •
NH3 used as desorption agent for desorbing Mo (IV) ions loaded on nanoparticles.
- •
Increase in initial NH3 concentration decreases the desorption Kd values.
- •
The maximum amount of Kd for adsorption was 3200 mL/g.
