碳纤维电极对水溶液中苯酚的电化学氧化处理

Electrochemical Oxidation of Aqueous Phenol at Carbon Fibre Electrode

制作了碳纤维电极,并将其应用于苯酚的氧化处理上。循环伏安实验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。碳纤维电极能克服传统碳电极的缺点,电极表面没有积垢,电极的重现性好。经过长时间恒电位氧化后,可以有效降低水溶液中苯酚的浓度。

The electrochemical oxidation of aqueous phenol at carbon fibre electrode was studied by cyclic vohammetry. The results showed that in the potential region of water stability, fine oxidation current curve can be obtained. The electricity of oxidation peak was partly linear with phenol concentration. Comparing with traditional carbon electrode, better results were obtained with the carbon fibre electrode. After a long time of the potentiostatic oxidation, the concentration of phenol can be reduced effectively.
