The present work describes the development of an electrochemical sensor for the simultaneous determination of Pd-Rh and Pt-Rh complexes using a bismuth-silver bimetallic nanofilm modified glassy carbon electrode. The electrochemical sensor was prepared by drop-casting bismuth-silver bimetallic nanoparticles on to glassy carbon electrode surfaces. The HRTEM microscopy and UV-Vis spectroscopy results of the bismuth-silver nanoparticles were compared with other work in literature. The developed nanosensor exhibited a linear working range of 0.4 - 1.4 ng/L for Pd-Rh and 0.8-1.2 ng/L for Pt-Rh DMG complexes, respectively. Very low detection limits (S/N = 3) of 0.19 ng/L for Pd (II), 0.2 ng/L Pt (II) and 0.22 ng/L for Rh (III) were obtained and the sensor was successfully applied to environmental samples.
