In the detection experiments, the scan rate is set at 0.3 V/s under the analysis of linear sweep voltammetry. On the cyclic voltammetry plot, each pair of clear redox peaks was observed for 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), and penta- chlorophenol. The potentials of the redox pairs were 1.218 and -0.460 V for 4-CP, 1.128 and -0.448 V for 2,4-DCP, and 1.037 and -0.473 V for PCP.

Dissimilatory Fe oxide reduction under anaerobic condition is a process which is an anaerobic respiration with Fe as the terminal electron acceptor. This anaerobic respiration showed important environmental significances. Dissimilatory Fe reducers can use diverse electron acceptors including many toxic heavy metals and metalloids such as Mn、Cr、Co insides Fe. So these toxic metals were detoxified or were immobilized reductively.

这种厌氧呼吸作用具有重要的环境学和地学意义，Fe还原微生物可利用除Fe以外的许多其它电子受体包括许多有毒重金属和类金属，如Mn、Cr、Co等，从而对这些有毒重金属起到还原解毒或还原固定的作用；还原过程还可促进一些有机污染物的降解； Fe氧化物的还原偶联着Si、P等元素的变化，对提高这些营养元素的有效性发挥着重要作用。

In the course of reduction at about 1000℃,Fe_2O_3 and then Fe_3O_4 was almostcompletely transformed into Wüstite within a few minutes prior to the formationof metallic iron;but the reduction of Wüstite to metallic iron lasted a much lon-ger time.

在1000℃左右的还原过程中，在金属铁出现之前，在数分钟内Fe_2O_3和Fe_3O_4几乎都已全部还原成浮士体，但后者还原成金属铁的阶段，则须经历数十分钟之久，因此后一阶段便成为还原过程中控制的一步。
