Abstract
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 (NO(2)(-)) which leads to the sensitive determination of NO(2)(-). Electrostatic repulsion between NO(2)(-) and Nf film is greatly decreased when Nf film is fully exchanged with cations.
摘要
Fe(bpy)(3)(2+)（其中 bpy = 2,2' 联吡啶）固定在 Nafion（Nf）修饰的玻碳电极上，显示出对亚硝酸盐（NO(2)(-))的优异电催化氧化作用，从而实现了对 NO(2)(-)的灵敏测定。当 Nf 膜完全被阳离子交换时，NO(2)(-)与 Nf 膜之间的静电排斥大大降低。
