苯酚溶液电解降解的过程分析及中间体的研究

电解降解有机污染物的方法由于其特殊的优点，已被广泛应用于包括含酚废水在内的废水处理中，以苯酚水溶液作为研究对象，以Ｔｉ／ＳｎＯ２＋Ｓｂ２Ｏ电极为阳极，对苯酚水溶液进行电解降解处理，对反应过程进行跟踪，并利用ＨＰ８４５３ＵＶ－Ｖｉｓ分光光度计和ＨＰ１１００液相色谱仪对不同反应时间的样品进行分析，作出了苯酚电解降解过程中不同反应时间的吸附曲线，获得了苯酚解的动力学方程，并对反应的机理及中间体进行了研究

Research on Process Analysis and Intermediate of Electrolytic Degradation Process of Phenol Water Solution

The electrolytic degradation has become a promising method of the prevention and treatment of wastewater recently because of its characteristic advantages. In this paper phenol water solution was chosen to be degraded by Ti/SnO 2 Sb 2O 3 electrodes used as anodes, HP8453 UV-Vis spectrometer and HP1100 HPLC were employed to analyze the samples sampled at the same intervals in the degradation process. The absorption curve of phenol solution at different degradation time was described, and the kinetic equation of degradation was solved in this paper. Furthermore, the mechanism and intermediate of this reaction process have been researched on in details. The existence of intermediate in the electrolytic process is studied by two means, namely, chromatograph and the UV absorption spectrum, and has been proved successfully. The kinetic curve of intermediate was also described.
