文摘
- •
Magnetic amine-crosslinked bio-adsorbent was prepared for nitrate uptake.
- •
The characters of adsorbent were determined by VSM, TGA, XRD, SEM, TEM, FT-IR and XPS.
- •
This novel bio-adsorbent could achieve rapid separation from effluents.
- •
Chemical regeneration of the saturated magnetic bio-adsorbent was conducted.
- •
The adsorption followed the pseudo second order model and Langmuir model.
