AB  - Glassy Carbon Electrode GCE was modified with different composites to increase the efficiency of analyzing trace Hg<SUP>2+</SUP> by cyclic voltammetry. The structure and composition of the modified GCE was processed using different methods for using Carbon Nanotubes CNT, Activated Carbon AC and C<SUB>60</SUB> on GCE to produce three modified electrodes CNT/GCE, AC/GCE and C<SUB>60</SUB>/GCE. The comparison study to choose the best modified electrode for detecting traces of Hg<SUP>2+</SUP> ion by calibration curve. A wide linear range and good repeatability were obtained for Hg<SUP>2+</SUP> detection by CNT/GCE in aqueous 0.1 M KCl as the supporting electrolyte, the relative standard deviation of three modified electrodes are better for CNT/GCE than AC/GCE and C<SUB>60</SUB>/GCE. The most modified electrode to detect the trace of Hg (II) in 0.1 M KCl as supporting electrolyte is CNT/GCE.
