  • Title: Reductive degradation of nitrobenzene in aqueous solution by zero-valent iron.
    Author: Mu Y, Yu HQ, Zheng JC, Zhang SJ, Sheng GP.
    Journal: Chemosphere; 2004 Feb; 54(7):789-94. PubMed ID: 14637335.
    Abstract:
    The reductive degradation of nitrobenzene (NB) by zero-valent iron was investigated. Experimental results showed that the degradation of NB was influenced by pH and NB concentration. The optimum pH value was found to be 3.0 for the reductive degradation of NB in the tested pH ranges of 3.0-12.0. The formation rate of aniline, a major reductive product of NB, followed zero-order kinetics at various pH levels. Furthermore, GC/MS analysis showed that aniline, azobenzene and azoxybenzene were the reductive products of NB by zero-valent iron. With the analysis of the products with GC/MS and FTIR, possible reductive pathways of NB by zero-valent iron were suggested.
