FENG Zhirong, JIAO Weizhou, LIU Youzhi, et al. Treatment of nitrobenzene-containing wastewater by iron-carbon micro-electrolysis[J]. CIESC Journal, 2015, (3): 1150-1155.
Nitrobenzene was selected as a model contaminant to examine the effects of initial concentration of nitrobenzene
dosage of iron
rate of iron/carbon and pH (pH<3.0) on removal efficiency of nitrobenzene by iron-carbon micro-electrolysis. The initial concentration of nitrobenzene determined the dosage of iron. The additional activated carbon could compete with degradation substrate on electron accepting
leading to a negative effect on the efficiency of electron usage
and decreased reduction efficiency of iron-carbon micro-electrolysis. Low pH could increase reaction rate of iron-carbon micro-electrolysis
and increasing pH during the reaction had a remarkable effect on formation and distribution of intermediate reduction products
