Mechanochemical remediation of PCB Contaminated Soil.
Chemosphere, 2016Co-Authors: Haizhu Wang, Jisu Hwang, Jun Huang, Kunlun Zhang, Kai Liu, Zhiguo CaoAbstract:Soil Contaminated by polychlorinated biphenyls (PCBs) is a ubiquitous problem in the world, which can cause significant risks to human health and the environment. Mechanochemical destruction (MCD) has been recognized as a promising technology for the destruction of persistent organic pollutants (POPs) and other organic molecules in both solid waste and Contaminated Soil. However, few studies have been published about the application of MCD technology for the remediation of PCB Contaminated Soil. In the present study, the feasibility of destroying PCBs in Contaminated Soil by co-grinding with and without additives in a planetary ball mill was investigated. After 4 h milling time, more than 96% of PCBs in Contaminated Soil samples were destroyed. The residual concentrations of PCBs decreased from 1000 mg/kg to below the provisional Basel Convention limit of less than 50 mg/kg. PCDD/F present in the original Soil at levels of 4200 ng TEQ/kg was also destroyed with even a slightly higher destruction efficiency. Only minor dechlorinations of the PCBs were observed and the destruction of the hydrocarbon skeleton is proposed as the main degradation pathway of PCBs.

CHEMICAL DECONTAMINATION OF PCB-Contaminated Soil
Chemosphere, 1997Co-Authors: Shin Taniguchi, Akihiko Murakami, Masaaki Hosomi, Akira Miyamura, Ryuji UchidaAbstract:PCB-Contaminated Soil was treated using the BCD (Base Catalyzed Decomposition) process to study the PCB removal performance of this process. NaHCO3 was augmented into the Soil to reduce PCB concentration. It was found that PCBs underwent partial dechlorination and PCB degradation, during which organic matter in the Soil performed as hydrogen donors. Test results indicated that a PCB removal of 99.79% was achieved by this process.
