Abstract: An electrochemical investigation of cadmium species has been carried out by using cyclic voltammetry (CV) at different modified glassy carbon electrodes (GCE). The modified CNT/GCE, C60/GCE and modified activated carbon (AC) on GCE as AC/GCE were used as working electrodes in CV. One application of these electrodes is detection of Cd(II) ion in blood medium using CV technique. Electrodes response was obtained for the oxidation and reduction peaks of Cd(II) ion in blood medium at modified CNT/GCE, C60/GCE, and AC/GCE. A well defined oxidation and reduction current peaks appeared at -0.54 and -0.67 V versus Ag/AgCl with a current enhancement and peak potential shift toward higher potential due to nano materials (CNT and AC) comparison with C60/GCE and bar GCE. Besides that, the presence of CNT or AC on the GCE in blood media caused an increase of the oxidation and reduction current peaks of Cd(II) ion (current enhancement) by about five times compared to the use of other modified electrodes. A linear relationship (R2=0.9567, Y=2779.9X+5.5598) was observed for the plot of current (mA) versus concentration range of 810-5 - 110-4 M of cadmium ion in blood medium using CNT and AC modified GCE. Based on the background noise of 50 data points, adjacent to the oxidation peak of Cd(II), and 3 s/slope, a detection limit of 810-5 M was determined. So it can be said that these modified electrodes could be used as good sensors in CV for the detection of traces of cadmium ion in blood medium.


Keywords: Sensors, Blood medium, Cd(II), CNT/GCE, C60/GCE, AC/GCE.
