Abstract
Fe-0-mediated reductive destruction of hazardous organic compounds such as chlorinated organic compounds (COCs) and nitroaromatic compounds (NACs) in the aqueous phase is one of the latest innovative technologies. In this pap er, rapid reductive degradation of COCs and NACs by synthesized nanoscale F e-0 in anaerobic batch systems was presented. The nanoscale Fe-0, character ized 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 condition s, which results in complete disappearance of the parent compounds from the aqueous phase within a few minutes. GC analysis reported that the main pro ducts of the dechlorination of TCE and CF were ethane and methane as well a s that most of the nitro groups in NACs were reductively transformed to ami ne groups. These results suggest that the rapid reductive destruction by na noscale Fe-0 is potentially a viable in situ or aboveground treatment of gr oundwater contaminated with hazardous organic compounds including COCs and NACs.
