文摘
- •
A novel magnetic chitosan modified by l-arginine was synthesized.
- •
The adsorption capacity and equilibrium time for Cu(II) were 2.13 mmol g−1 and 13 min, respectively.
- •
The adsorbent was easily separated from aqueous solution in 2 min by external magnetic field.
- •
The adsorbent exhibited good adsorption performance after five regeneration cycles.
