The electrochemical behavior of cadmium ions on glassy carbon electrodes in two-step processes involves reduction at -0.95V and oxidation at -0.6 VVs. Ag/AgCl electrodes has been reported. The cyclic voltammetry data for cadmium ions using potassium chloride as supporting electrolyte in 50 % Demso-H2O (V/V) shows enhanced currents in the absence and presence of ligand N-(benzol [d] thiazol-2-yl)-3-(2-hydroxybenzylidene) hydrazinyl)-3-oxopropanamide(H₂BTHB). Different cyclic voltammetry solvation data were obtained for cadmium ions in the absence and presence of (H₂BTHB).The obtained cyclic voltammetry and thermodynamic data prove the complexation reaction between the cadmium ions and the used ligand.
