dc.description.abstract | Zero valent iron (ZVI), the primary reactive material in several permeable reactive barriers, is often oxidized to ferrous or ferric iron, resulting in decreased reactivity with time. Iron reducing bacteria can reconvert the ferric iron to its ferrous form, prolonging the reduction of chlorinated organic contaminants. In this study, the reduction of Fe(II, III) oxide and Fe(III) oxide by a strain of iron reducing bacteria of the group Shewanella alg\a BrY(S. alga BrY) was observed in both aqueous and solid phases. S. alga BrY preferentially reduced dissolved ferric iron over the solid ferric iron. In the presence of iron oxide the Fe(II) ions reduced by S. alga BrY efficiently reduced trichloroethylene (TCE). On the other hand, Fe(II) produced by S. alga BrY covered the reactive surfaces of ZVI iron filings and inhibited the reduction of TCE by ZVI. The formation of precipitates on the iron oxide or Feo surface was confirmed by scanning electron microscopy. The results suggest that iron-reducing bacteria in the oxidized Feo barriers can enhance the removal rate of chlorinated organic compounds and influence on the long-term performance of Fco reactive barriers. | - |
