Abstract in English
The amperometric sensor based on a silver nanowire (80 nm in diameter Ag NW) array electrode was fabricated and characterized with scanning electron microscope (SEM). The electrode showed good electrocatalytic activity for reduction of hydrogen peroxide. The effects of the applied polarization potential, pH, time interval between successive injections of analyte, injection volume and H2O2 concentration in a single injection on the electrochemical performance of the sensor were studied. It was found that the optimized operating conditions for the proposed sensor are: the potential of −200 mV, pH between 7.4 and 9.0, 60 s time interval, 10 µL injection volume, and 500 µM H2O2 in single injection. The proposed Ag NW array sensor is free of interference from ascorbic acid, uric acid and glucose.
