Mechanisms and influencing factors of the deoxidization of nitrobenzene by zero-valent iron

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.Experiment shows that under laboratorial temperature and acidic conditions,the deoxidization rate of nitrobenzene could reach 97.4% when pH is 6.0—7.5,and Eh is-172—266 mV.
