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.

利价铁的还原性质,将难生物的有机物基苯先还原生成亚基苯,然后再进一步还原成可生物的苯胺。

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.

由机理分析和宏CODCr率难易程度比较可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。
