  • 摘要: 为了强化MW-Fenton法有机废水处理技术,向MW-Fenton体系中加入Cu(Ⅱ),组成MW-Cu(Ⅱ)-Fenton体系,并以间硝基苯胺(m-NA)为底物,对该体系进行了研究。首先考察了包括MW-Cu(Ⅱ)-Fenton体系在内的6种污水处理方法对m-NA配水的处理效果,并对其进行了准一级动力学对比。结果表明:MW-Cu(Ⅱ)-Fenton氧化法具有最大的反应速率常数(0.379 min-1),是MW-Fenton法(0.279 min-1)的1.36倍;Fe(Ⅱ)为MW-Cu(Ⅱ)-Fenton氧化法中的核心催化剂,Cu(Ⅱ)为辅助催化剂。在此基础上考察了pH,nH2O2/nFe(Ⅱ)和对MW-Cu(Ⅱ)-Fenton体系的影响,并进行了优化,根据实验结果,确定最佳条件为:pH=3.0,=0.20 mmol/L,nH2O2/nFe(Ⅱ)=80,=0.3 mg/L。最后,利用荧光分光度法测定了6种氧化体系中羟基自由基(·OH)的相对生成量,对比结果表明Cu(Ⅱ)是通过加快MW-Fenton体系中·OH的生成速率而起作用的。
    Abstract: In order to enhance the microwave-Fenton(MW-Fenton) process, Cu(Ⅱ) was added into the process to form MW-Cu(Ⅱ)-Fenton process. m-nitroaniline(m-NA) was chosen as the target pollutant. Firstly, the treatment effects of m-NA in six wastewater treatment methods respectively(MW-Cu(Ⅱ)-Fenton process included) were examined via the pseudo first-order kinetics comparison. The results show that MW-Cu(Ⅱ)-Fenton process has the largest reaction rate constant(0.379 min-1) which is 1.36 times larger than that in MW-Fenton process(0.279 min-1). Fe(Ⅱ) is the core catalyst in MW-Cu(Ⅱ)-Fenton process while Cu(Ⅱ) is the assistant one. Next, the effects of four parameters(pH,[Fe(Ⅱ)],nH2O2/nFe(Ⅱ),[Cu(Ⅱ)]) on MW-Cu(Ⅱ)-Fenton process were studied and optimized. According to the results, the optimal conditions were pH=3.0,=0.20 mmol/L, nH2O2/nFe(Ⅱ)=80 and=0.3 mg/L. Finally, the relative generation amount of hydroxyl radicals(·OH) was measured and compared by fluorescence spectrophotometry. The results reveal that the assistant catalyzed function of Cu(Ⅱ) is performed by accelerating the generation rate of·OH in MW-Cu(Ⅱ)-Fenton process.
