title: Efficient sensing of nitrite by Fe(bpy)3(2+) immobilized Nafion modified electrodes.
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.
