摘要
A sensitive electrochemical sensor was fabricated based on Fe3O4/ZIF-4 nanoparticles (NPs) modified screen printed graphite electrode (Fe3O4/ZIF-4/SPGE) for detection of bisphenol A. Characterization of Fe3O4/ZIF-4 NPs was performed by EDX, MAP, XRD, FT-IR, FESEM, TEM and TGA. The performance of the designed electrochemical sensor was tested by voltammetric techniques. Fe3O4/ZIF-4/SPGE exhibited very acceptable electrocatalytic activities for oxidizing bisphenol A via considerable increase of the peak currents and changes in the peak potentials towards less positive potentials. Fe3O4/ZIF-4/SPGE demonstrated excellent sensing performance with the wider linear ranges (0.06-300.0 mu M), lower limit of detection (LOD) (0.015 +/- 0.001 mu M), and high sensitivity (0.1274 mu A mu M-1). The practical applicability has been demonstrated through the detection of bisphenol A in different real samples.
