| 摘 要： | 采用电沉积的方式将纳米金固载在玻碳电极表面,制得纳米金修饰玻碳电极(NG/GCE)。研究了去甲肾上腺素(NE)在NG/GCE的电化学行为,发现NG/GCE不仅对NE有良好的催化和富集作用,而且能将NE和抗坏血酸(AA)的循环伏安氧化峰很好地区分开,可在抗坏血酸共存下选择性测定NE。

| Abstract: | Glass carbon electrode modified with gold nanoparticles(NG) were called NG/GCE.The electrode(NG/GCE) were used for the determination of Epinephrine(EP).A very large increase in the current for the oxidation of EP when compared with the bare glass carbon electrode has been observed at NG/GCE electrode.On the other hand,Which was successfully used for the selective determination of Epinephrine(EP) in the presence of ascorbate(AA)? |
