A novel technique for the fabrication of Bi–Sb composite film
electrode, which was prepared in situ on a glassy carbon substrate
electrode, was demonstrated. The application of the Bi–SbFE for
measuring trace cadmium(II) was developed. The Bi–SbFE revealed
better electroanalytical performance than the bismuth film or antimony
film electrodes. Due to the early stage of our investigations,
it is inevitable to conduct further work oriented toward the study
of the application of the Bi–SbFE to other potentially interesting
inorganic and organic analytes.
