Abstract

In this work, a new type of micro-electrolysis technology using combined materials containing fly ash, iron scraps and rare earth Gd on the treatment of toxic and harmful nitrobenzene wastewater was presented. Fly ash was applied instead of activated carbon in the combined materials and single-factor experiment was conducted to determine and optimize the relevant influence factors on the removal rate of nitrobenzene. Both the main and minor factors and the optimum levels influencing the nitrobenzene removing property were determined via the orthogonal experimental design. The results showed that the rank of each factor for removing ratio of nitrobenzene from better to less was respectively: pH, rare earth Gd dose, mass ratio of fly ash and iron and reaction time. The optimal combined conditions were 2, 12mL, 2:1and2.0 h respectively. The experiment data of the removal rate of nitrobenzene was 83.3%. In addition, the removal efficiency was improved by 13.6% with the addition of rare earth Gd.
