论文摘要
乙氧基甲氧基(NPE 10)是一种非离子表面活性剂,它是从乙氧基烷基苯酚合成的。 NPE-10在废水中的积累将危害生态系统和人类。目前,通过技术的进步,NPE 10可以通过使用电化学处理来间接降解。因此,这项研究旨在使用CE(IV)离子介质通过介导的电化学氧化(MEO)评估NPE 10的潜在电降解。此外,还观察到Ag(I)离子催化剂对NPE 10降解的MEO性能的影响。通过伏安法技术评估了降解NPE 10中MEO技术的效力,并通过滴定法和LC-MS分析确认。结果表明,在没有Ag(I)离子催化剂的情况下,MEO降解NPE 10为85.93%。此外,当应用Ag(I)离子催化剂时,NPE 10降解中MEO的性能提高到95.12%。使用BA(OH)2的背部滴定证实了CO2的形成46.79%。氧化还原滴定显示,降解有机化合物的总数增加了42.50%,这是通过在LC-MS色谱图中形成两个新峰来强调的。总而言之,我们的结果证实了MEO技术对NPE-10降解的潜力。
Nonylphenol ethoxylate (NPE 10) is a non ionic surfactant which is synthesized from alkylphenol ethoxylate. The accumulation of NPE-10 in wastewater will endanger the ecosystem as well as human being. At present, by an advancement of technology NPE 10 can be degraded indirectly by using an electrochemically treatment. Thus, this study aimed to evaluate the potential electrodegradation of NPE 10 by mediated electrochemical oxidation (MEO) using Ce(IV) ionic mediator. In addition, the influence of Ag(I) ionic catalyst in the performance of MEO for degradation of NPE 10 was also observed. The potency of MEO technology in degradation NPE 10 was evaluated by voltammetry technique and confirmed by titrimetry and LC-MS analyses. The results showed that in the absence of Ag(I) ionic catalyst, the degradation of NPE 10 by MEO was 85.93 %. Furthermore, when the Ag(I) ionic catalyst was applied, the performance of MEO in degradation of NPE 10 was improved to 95.12 %. The back titration using Ba(OH)2 confirmed the formation of CO2 by 46.79 %. Whereas the redox titration shows the total of degradation organic compounds by 42.50 %, which was emphasized by formation of two new peaks in LC-MS chromatogram. In summary, our results confirm the potential of MEO technology for NPE-10 degradation.
