| 摘 要： | 考察了NaCl、AlCl3、Na2SiO3、CuSO44种均相催化剂对超声波(US)/铁炭微电解(FCME)协同体系降解硝基苯的催化效果,结果表明,CuSO4的催化效果最好,在体系反应液初始pH为3.0,混合填料投加量为5.0 g/L(铁炭质量比为1∶1),CuSO4投加量为800 mg/L时,体系对硝基苯的降解率达到99.2%,但溶液COD值仅下降了24.6%,矿化效果一般,红外光谱分析表明降解体系的主要中间产物为苯胺。

| Abstract: | The enhanced effects of homogeneous catalysts on nitrobenzene degradation within ultrasound/iron-carbon microelectrolysis system were investigated.The results showed that CuSO4 exhibited the best catalytic efficiency compared to NaCl,AlCl3,Na2SiO3.The removal efficiency of nitrobenzene reached 99.2% with an initial pH of 3.0,5.0 g/L iron/carbon mixed padding(1:1 mass ratio),and 800 mg/L of CuSO4.However,the COD of the solution only decreased 24.6% after the reaction.The infrared spectrum analysis indicated that aminobenzene was the major intermediate product during the degradation process. |
