| 摘 要： | 用循环伏安法制备了铁氰化铜修饰玻碳电极（CuHCF）。对CuHCF膜电极的电化学行为进行了表征，并研究了电极对亚硝酸根的电催化氧化作用。结果表明亚硝酸根在CuHCF膜电极上有明显的催化作用，而且电催化峰电流与NO2-浓度在2．0×10^-6～2．5×10^-3mol／L范围内．催化峰电流与浓度呈良好的线性关系。

| Abstract: | Cupric hexacyanoferrate modified glassy carbon electrode is prepared with cyclic voltammogram method, and the electrochemcal behavior of nitrite at the modified electrode is studied. Experimental results show that electrocatalytic oxidation of nitrite on CuHCF film modifid electrode was described. The modified electrode can be used for the determination of nitrite in the concentration range of 2.0 ×10^-6 ~ 2.5 ×10^-3 mol/L. |
