Abstract

In this work, a new type of micro-electrolysis technology using combined materials containing fly ash, iron scraps and lanthanon Gd on the treatment of toxic and harmful aniline 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 aniline. Both the main and minor factors and the optimum levels influencing the aniline removing property were determined via the orthogonal experimental design. The results showed that the rank of each factor for removing ratio of aniline from better to less was respectively: pH, lanthanon Gd dose, reaction duration and mass ratio of fly ash and iron. The optimal combined conditions were 3.50, 16 mL, 1.50 h and 1:2, respectively. The experiment data of the removal rate of aniline was 86.7%. In addition, the removal efficiency was improved by 15.3% with the addition of lanthanon Gd.
