Abstract
Bituminous coal-based magnetic activated carbon (MAC) was prepared, characterized, and used successfully for removal of cyclic volatile methylsiloxanes (cVMSs) from treated landfill leachate. Batch adsorption studies were performed at different adsorption dosages and contact times. With adsorptive dosage of 0.75g/L and contact time of 60min, the removal efficiencies achieved by MAC for octamethylcyclotetrasiloxane (D4), decamethylcyclopentasiloxane (D5), and dodecamethylcyclohexasiloxane (D6) are 100, 82.8, and 71.4%, respectively. The specific magnetization coefficients of MAC before and after adsorption are 4.6×10-7 and 5.2×10-7m3/kg, between 1.26×10-7 and 3.8×10-5m3/kg, which suggests that MAC can be recycled by the high-intensity magnetic separators.
