Electrochemical determination of nitrite at a bare glassy carbon electrode; why chemically modify electrodes?
The oxidation of nitrite was studied at a bare glassy carbon (GC) electrode in aqueous solution using cyclic voltammetry, square wave voltammetry and chronoamperometry. A mechanism for the electrode reaction is proposed. A limit of detection (LOD) of 4 × 1 0- 7 M was obtained for amperometry and thi...

| description | The oxidation of nitrite was studied at a bare glassy carbon (GC) electrode in aqueous solution using cyclic voltammetry, square wave voltammetry and chronoamperometry. A mechanism for the electrode reaction is proposed. A limit of detection (LOD) of 4 × 1 0- 7 M was obtained for amperometry and this is evaluated with reference to literature reports for NO2- detection; in particular, the possible merits of using chemically modified electrodes as compared to 'bare' unmodified electrodes are critically assessed. © 2009 Elsevier B.V.
