采用电沉积的方法,在玻碳电极表面快速电沉积均匀分布的铁氰化镍/Naion纳米粒子。用X射线能量色散光谱图(EDX)和扫描电镜(SEM)对样品进行了表征,然后采用循环伏安法对该修饰电极进行电化学研究。结果表明:该电极对葡萄糖具有良好的电催化氧化性能,对葡萄糖响应的线性范围为1.560×10~(-6)~10.32×10~(-3)mol/L(R~2=0.999),检出限为1.2μmol/L(S/N=3)。制得的修饰电极对葡萄糖的电催化具有灵敏度高、重现性好和选择性强的优点。

Electrodeposition was used to rapidly electrodeposit Ni (II) / Niion nanoparticles on the surface of glassy carbon electrode. The samples were characterized by X-ray energy dispersive spectroscopy (EDX) and scanning electron microscopy (SEM), and then the modified electrode was electrochemically studied by cyclic voltammetry. The results showed that the electrode exhibited good electrocatalytic activity for the oxidation of glucose with a linear range of 1.560 × 10 -6 -6.32 × 10 -3 mol / L (R 2 = 0.999) The detection limit was 1.2μmol / L (S / N = 3). The prepared modified electrode has the advantages of high sensitivity, good reproducibility and selectivity to the electrocatalysis of glucose.
