Abstract EN
Polychlorobiphenyls (PCBs) have been identified as environmental hazards for years.
Due to historical issues, a considerable amount of PCBs was released deep underground in Canada.
In this research, a nanoscale zero valent iron- (nZVI-) aided dechlorination followed by biosurfactant enhanced soil washing method was developed to remove PCBs from soil.
During nZVI-aided dechlorination, the effects of nZVI dosage, initial pH level, and temperature were evaluated, respectively.
Five levels of nZVI dosage and two levels of initial pH were experimented to evaluate the PCB dechlorination rate.
Additionally, the temperature changes could positively influence the dechlorination process.
In soil washing, the presence of nanoiron particles played a key role in PCB removal.
The crude biosurfactant was produced using a bacterial stain isolated from the Atlantic Ocean and was applied for soil washing.
The study has led to a promising technology for PCB-contaminated soil remediation.
