2,2′-Dichlorobiphenyl (PCB4); 3,3′,4,4′-Tetrachlorobiphenyl (PCB77); Degradation mechanism; Dielectric barrier discharge (DBD); Polychlorinated biphenyls (PCBs); Soil remediation Soil contaminated by PCBs from the electronic processing industries has attracted global concern because of their potentially persistent risks to human and ecological health. In this study, remediation of PCBs polluted soil using dielectric barrier discharge plasma (DBD) focused on 3,3′,4,4′-tetrachlorobiphenyl (PCB77) and 2,2′-dichlorobiphenyl (PCB4). About 90 % of PCB77 and PCB4 were degraded under input power of 120 W within 30 min. The carbon dioxide mineralization of PCB77 achieved at 18.2 % in 10 min treatment. Greater PCBs degradation was obtained with higher input power, lower moisture content, |
