In this report, applicability of reductive dechlorination method of Polychlorinated Biphenyl (PCB) with zero-valent metals under ambient temperature is evaluated theoretically and experimentally. Thermodynamic data predicts successful dechlorination of PCB coupling with zero-valent iron reaction. However, experimental data suggests further reactivity of iron powder would be required to realize effective reaction rate for chlorinated aromatic compounds. Laboratory experiments using PCBs-contaminated soils were conducted, and dechlorination of PCB was observed with five different types of modified iron powder in 30 days experiment period. Iron mixing method does not require plant systems, and is vest applicable for detoxification of PCBs in contaminated soils.
