Abstract The present study reports synthesis of BaFe12O19 nanoparticles by sol gel technique followed by its characterization using Energy dispersive X-ray spectroscopy (EDS), X-Ray diffraction (XRD), field emission scanning electron microscopy (FESEM), vibrating sample magnetometer (VSM) analysis, and Fourier-transform infrared spectroscopy (FTIR). The BaFe12O19 nanoparticles have been applied to construct a modified graphite screen-printed electrode (GSPE). BaFe12O19/GSPE has been applied as a working electrode in the analysis of tramadol and acetaminophen by voltammetric techniques. The BaFe12O19/GSPE showed a good selectiveness for analysis of tramadol in the presence of acetaminophen with the separated peak potentials at ~ 230 mV, and ~ 700 mV, respectively. Excellent linear calibration curves, ranging from 0.08 to 500.0 µM for tramadol and from 5.0 to 500.0 µM for acetaminophen, with detection limits of 0.025 and 1.5 µM were obtained.
