介孔碳修饰石墨电极处理模拟硝基苯废水
Treatment of simulated nitrobenzene wastewater by mesoporous carbon-modified graphite electrode
摘要
Abstract
The mesoporous carbon-modified graphite electrode was prepared by hydrothermal synthesis-high temperature carbonization-coating method and used for electrochemical treatment of simulated nitrobenzene wastewater. The effects of wastewater pH,current density and electrolyte amount were investigated. The characterization results showed that there were many mesoporous structures on the surface of the modified electrode,so that the nitrobenzene removal rate and aniline yield by it were higher than those by graphite electrode. The experimental results showed that under the conditions of wastewater pH 7.0,current density 15 mA/cm2,electrolyte Na2SO4 amount 1.775 g/L, electrolyzation time 3.0 h and initial nitrobenzene mass concentration 100 mg/L,the removal rate of nitrobenzene was up to 99.6% and the aniline yield reach 45.54 mg/L.关键词
