Effect of Common Dissolved Ions on the Reduction of Nitrobenzene by Sucrose-Modified Zero-Valent Iron

Abstract:

NB reduction with NZVI will be effected by factors. In this study, batch experiments were carried out to evaluate the single and combined actions of common dissolved ions including HCO3-, Cl-, SO42-, NO3-, Mg2+ and Ca2+. The results showed that the removal efficiency of NB was enhanced with the increase of the concentration of added HCO3-, Cl-, SO42-, NO3- as a descending order, and SO42- would be an inhibitor when its concentration was lower than 250 mg/L. Mg2+ and Ca2+ themselves had no obvious influences on NB reduction with SM-NZVI, but they could weaken the positive effects of other coexisting ions like Cl- and SO42-. Coexistence of these dissolved ions would promote metal carbonate precipitations and thus made against NB degraded and aniline produced.
