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.

利用零价铁性质,将难生物降解有机物基苯先生成亚基苯,然后再进一步成可生物降解苯胺。

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.

由机和宏观CODCr降解率难易程度比较可知高铁酸根与对氯苯酚、苯胺反应比与基苯反应更加容易进行。
