A multifunction magnetic carbonaceous adsorbent (MBM/OH/BC) was synthesized by facile NaOH and ball-milling co-modified biochar, and applied for removing Cd 2+ in water. The results showed MBM/OH/BC exhibited excellent adsorption capacity (183.59 mg/g for Cd 2+), short equilibrium time (60 min) and good reusability (the declining efficiency <20% after four …
