去甲肾上腺素在碳纤维修饰电极上的电化学行为研究

The electrochemical study of norepinephrine on DNA and nano-gold double modified carbon fibre electrode

利用电沉积的方法制备DNA、纳米金双层修饰碳纤维电极。该电极对去甲肾上腺素电化学氧化反应具有催化作用。研究了磷酸缓冲溶液浓度和pH值对NE的电化学行为的影响。该修饰电极可以在共存抗坏血酸情况下选择性测定NE。

The DNA and nano-gold double modified carbon fibre electrode, which can catalyze oxidation reaction of norepinephine, was prepared by electrodeposition. The effect of the concentration of phosphate buffer solution and pH value on the electrochemical behavior of norepinephine was studied. This modified electrode can be used to determine the concentration of norepinephine in the presence of ascorbic acid.
