摘要：
Fe(bpy)(3)(2+) (where bpy = 2,2' bipyridyl) immobilized Nafion (Nf) modified glassy carbon electrodes were prepared and they showed excellent electrocatalytic oxidation of nitrite (NO2-) which leads to the sensitive determination of NO2-. Electrostatic repulsion between NO2- and Nf film is greatly decreased when Nf film is fully exchanged with cations.
