In this study, it is the purpose to determine the destruction efficiency of PCBs for various kinds of iron compounds. Fe, Fe3C, α-Fe2O3, Fe3O4, α-FeOOH and so on, were used as iron compounds. 200μg of PCBs (a mixture of Kanechlor-400 and 600) was heated at 250-350°C with each iron compounds (0.1g) in a sealed glass ample. Fe3C had the highest activity for decomposition of PCBs among the iron compounds under the experimental conditions. It was found that the combination of the carbon and iron contributed to the decomposition of PCBs.
Next, the destruction experiments of PCBs were performed using a tube type reactor to understand the effect of atmospheric condition on PCBs destruction. The decomposition ratio was high using both Fe3C and the iron powder pretreated by H2 gas under the N2 and the N2+O2 atmosphere.
