By the deoxidization of zero-valent iron,nitrobenzene,an organic compound hard to be biodegraded,can be deoxidized to nitrosobenzene,and further to aniline,which is easily biodegraded.

利用零价铁的还性质,将难生降解的有基苯先还生亚基苯,然后再进一步还生降解的苯胺。

On the basis of mechanism analysis and compare of CODCr degradation rate, parachlorophenol and aniline were found to be easier degraded by ferrate than nitrobenzene.

由理分析和宏观CODCr降解率难易程度比较知高铁酸根与对氯苯酚、苯胺的反应比与基苯的反应更加容易进行。
