摘要
本文以十二烷基苯磺酸钠和十二烷基磺酸钠为研究对象 ,在最佳的物理化学条件下 ,利用紫外光谱、红外光谱和气相色谱 质谱联用等仪器分析和化学分析的方法研究了电催化降解新技术去除废水中阴离子表面活性剂的机理。实验结果表明。在羟基自由基 (·OH )的氧化分解作用下 ,十二烷基苯磺酸钠和十二烷基碘酸钠先降解为丁烷 ,最终均矿化为CO2 、H2 O和SO42 - 。
In this paper, a new method for the treatment of wastewater containing anion surfactants by electrogenerated hydroxyl radical(·OH) in the OFR has been established. Anion surfactants for dodecylbenzene sulphonic acid sodium(DBS)and dodecyl sulphonic acid sodium (DDS)are selected as model polutants to study their degradation mechanism in the OFR. Under the optimal conditions, the results from IR, UV and GC MS ets.analysis showed that DBS and DDS were first oxidized to small molecules and finally mineralized to CO 2,H 2O and SO 4 2- etc..
