Degradation of nitrobenzene by bacterial dissimilatory reduction of iron oxides |
|
|
Abstract Experiments were conducted to investigate the biological dissimilatory reduction process of iron oxides and characteristics and efficiency of nitrobenzene degradation in subsurface environment. The results indicated that iron reducing microbial could degrade nitrobenzene; and the nitrobenzene removal efficiency was over 68.5% in 100h. Nitrobenzene showed higher removal efficiency in the bacterial dissimilatory reduction process of iron oxides; the maximum removal efficiency was observed at the goethite concentration of 0.3mg/L, and it was up to 78.5%. There was an apparently correlation between iron oxides reduction and nitrobenzene degradation.
