Abstract

A carbon sphere-modified glass carbon electrode was prepared by employing cyclohexanol as a solvent to disperse the carbon spheres efficiently. The resulting electrode exhibits excellent sensitivity to cadmium(II), and a detection limit of 10−10 mol/L has been obtained, which is one order of magnitude lower than those obtained by other electrodes. Along with immunity from interference of other metal ions, the wide determination range and good linear correlation coefficient would be beneficial to applications of the electrode.
