Preparation of ultrafine magnetic biochar and activated carbon for ...
Ball milling was used to prepare two ultrafine magnetic biochar/Fe 3 O 4 and activated carbon (AC)/Fe 3 O 4 hybrid materials targeted for use in pharmaceutical removal by adsorption and mechanochemical degradation of pharmaceutical compounds. Both hybrid adsorbents prepared after 2 h milling exhibited high removal of carbamazepine (CBZ), and were easily separated magnetically.
