Effect of iron (Ⅲ) reduction on Cr (Ⅵ) reduction in paddy soil

摘要：

Microbial Fe (Ⅲ) reduction is important in chromate reduction. One possible mechanism may be that iron reduction is first carried out by the microbial community and Fe (Ⅱ) produced in this reaction then serves as an electron acceptor during the reduction of chromate. Thus the ferrous iron is reconverted into its ferric form. Until chromate is depleted, the ferrous iron concentration is increased in soil slurries. This mechanism has important implications in the remediation of chromate pollution by the stress on iron reduction.
