How to remove harmful substances from water with the help of biochar? The efficient separation of biochar or other adsorbents from the treated solutions is a challenge.
Adsorption is a widely used technique for the removal of pollutants in liquid or gaseous effluents.
Among the proposed adsorbent materials, biochar is considered a low-cost effective adsorbent.
Magnetic separation method is an efficient, fast and low-cost technique for the recovery and the reuse of adsorbents from the medium after the adsorption treatment of pollutants is completed.
