文摘
- •
Ferromagnetic mediums were anchored into AC, resulting in good magnetic response.
- •
The Cr(VI) adsorption of CoFe2O4/AC was more effective than the initial AC.
- •
CoFe2O4/AC could be separated and retrieved easily by an outer magnet after Cr(VI) adsorption.
- •
The pH, temperature and initial Cr (VI) concentration affected Cr(VI) adsorption.
- •
The adsorptive behavior for Cr (VI) of CoFe2O4/AC conformed to the Freundlich model.
