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.

由机理分析和宏观CODCr降解率难易程度比较可知根与对氯酚、应比与硝基应更加容易进行。

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.

利用零价还原性质,将难生物降解有机物硝基先还原生成亚硝基,然后再进一步还原成可生物降解。
