| Abstract | The fabrication and surface morphology of methylene blue (MB)/perfluorosulfonated ionomer (Nafion) modified microcylinder carbon fiber electrode were studied. The stability of the modified electrode is good. The extraction coefficient K of MB between Nafion film and solution is similar to 110, and the diffusion coefficient of MB in Nafion film is similar to 5.3 x 10(-9) cm(2)/s. The MB/Nafion modified microcylinder electrode shows significant electrocatalytic activity for the oxidation of hemoglobin in weak acid media; it can be used for the determination of hemoglobin in the range of 5.0-50 mu M with a relative standard deviation of 3.5% at 6.0 mu M HB. A satisfactory result has been obtained for the determination of hemoglobin in clinical blood samples. |
