碳纳米管电极对水溶液中苯酚的电化学氧化处理

Electrochemical Oxidation of Aqueous Phenol at Carbon Nanotube Electrode

制作了多壁碳纳米管电极,并将其应用于苯酚的氧化处理上.结果发现有很好的氧化峰出现在电位窗口内,峰电流在一定范围内与苯酚的浓度成良好的线性关系.长时间恒电位氧化实验表明,能克服传统碳电极的缺点,电极表面没有积垢,电极的重现性较好,可以逐渐将苯酚氧化.

To investigate the effects of human soluble TRAIL（sTRAIL） on cell growth and apoptosis of hepatocellular carThe electrochemical oxidation of aqueous phenol at pure carbon nanotube electrode has been studied by cyclic voltammerry. The results have shown that in the potential region of water stability, fine oxidation current curve can be obtained. The electricity of oxidation peak is partly linear with phenol concentration . Comparing with traditional carbon electrode ,better results have been obtained with the pure carbon nanotube electrode. Depending on it, it is possible to obtain the complete combustion of phenol to CO2, which can avoid electrode fouling and poor repeatability.
