- •
Chemically modified magnetic chitosan microspheres were prepared and used for Cr(VI) removal.
- •
Its maximum adsorption capacity was 233.1 mg/g at pH 2.5 and 25 °C.
- •
The adsorbent exhibited strong acid resistance and a magnetic responsive nature.
- •
The adsorbent with 95.6% desorption efficiency had a good reusability.
