Effect of Common Dissolved Ions on the Reduction of Nitrobenzene by Sucrose-modified Zero-valent Iron
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.
