Abstract:
Poly ( aniline_luminol ) composite nanowires were synthesized by chemical oxidation using ammonium peroxydisulfate. In contrast to the maximum fluorescence emitting wavelength of luminol at 425 nm, the maximum fluorescence emitting wavelength of the polymeric luminol in the composite nanowires was red shifted to 465 nm obviously. The poly ( aniline_luminol) composite nanowires were modified on graphite electrode surface by drop coating, forming a stable poly ( aniline_luminol ) composite nanowires film. The composite nanowires film modified electrode presented favorable electrochemiluminescence ( ECL ) performances, and the ECL response could be enhanced by hydrogen peroxide. Under the optimized experimental conditions, the modified electrode provided a linear range of 5. 0×10-9-1. 0×10-5 mol/L for the detection of hydrogen peroxide with a detection limit of 2 ×10-9 mol/L.
