Adsorptive performance of coal based magnetic activated
carbon for perfluorinated compounds from treated landfill
leachate effluents
coal activated
charcoal powderCoal based powder Magnetic activated
carbon (MAC) were prepared, characterized and used
successfully for adsorption of PFCs in treated landfill
leachate effluents. The morphologies and surface
chemistries of MAC were studies by N2 gas adsorption
isotherms, SEM, and Lakeshore 7300 vibrating sample
magnetometer. The surface areas (SBET), the Langmuir
surface area (SLangmuir), the micropore volume and the
total pore volume of MAC were calculated according to the
corresponding N2 isotherms. Batch adsorption studies were
performed at different adsorption dosage and contact
time. With 8 g/150 mL adsorption dosage and 120 min
contact time, after adsorption by MAC, the removal
efficiencies of PFHxA, PFHpA, PFOA, PFNA and PFDoA in
leachate samples can reach 72.8–89.6%, respectively. The
MAC can be recycled by the high-intensity magnetic
separators. carbon.com/">granular activated carbon suppliers
