Abstract

Fe-0-mediated reductive destruction of hazardous organic compounds such aschlorinated organic compounds (COCs) and nitroaromatic compounds (NACs) inthe aqueous phase is one of the latest innovative technologies. In this paper, rapid reductive degradation of COCs and NACs by synthesized nanoscale Fe-0 in anaerobic batch systems was presented. The nanoscale Fe-0, characterized by high specific surface area and high reactivity, rapidly transformed trichloroethylene (TCE), chloroform (CF), nitrobenzene (NB), nitrotoluene(NT), dinitrobenzene (DNB) and dinitrotoluene (DNT) under ambient conditions, which results in complete disappearance of the parent compounds from the aqueous phase within a few minutes. GC analysis reported that the main products of the dechlorination of TCE and CF were ethane and methane as well as that most of the nitro groups in NACs were reductively transformed to amine groups. These results suggest that the rapid reductive destruction by nanoscale Fe-0 is potentially a viable in situ or aboveground treatment of groundwater contaminated with hazardous organic compounds including COCs andNACs.
