Novel cadmium oxide nanoparticles based sensor for the detection of penicillamine (PA) in aqueous solution has been developed. Cyclic voltammetry at potential range -1.1 to 1.1V from aqueous buffer solution (pH 7) containing CdO produced a well-defined cadmium oxide nanoparticles deposited on the surface of glassy carbon electrode. The Differential pulse voltammetry detection of penicillamine is carried out at 0.451V in buffer solution with pH 7. Cadmium oxide nanoparticles have many advantageous such as remarkable catalytic activity, simple preparation procedure and long-term stability of signal response during of penicillamine oxidation.
