文摘
- •
A quaternary ammonium salt modified chitosan magnetic adsorbent has been prepared.
- •
This adsorbent can be efficient removal of methyl orange (MO) and Cr(VI) from water.
- •
MO bears more affinity to this adsorbent than Cr(VI).
- •
This adsorbent has short adsorption time and rapid separation speed from water.
- •
This adsorbent can be efficient regenerated and reused after saturated adsorption.
