Abstract: Cu (II) complex of novel Schiff base ligand derived from 2-hydroxy-2 methylpropiophenone and sulphamethazine sulpha drugs has been synthesized and characterized by various experimental and theoretical tools. The electrochemical behavior of sulpha drugs-Schiff base and its copper (II) Complex at a glassy carbon electrode were examined in the BR universal buffer and phosphate buffer of various pH levels (5.0-8.2) containing 10-3 mM examined compounds in various solvents. The cyclic voltammograms of the Schiff base ligand exhibited an irreversible diffusion-controlled cathodic step within the all pH range and the Cu (II) complex displayed a quasi-reversible redox process due to Cu (II)/Cu (I) process. The effects of solvent, buffer, sweep rate and pH are also studied on CV variables. Kinetic parameters like as charge transfer coefficient (αn), diffusion coefficient (D01/2) and rate constant (K0f, h) are also calculated from cyclic voltammograms.
