Synthesis And Characterization Of Copper(II) Carboxylate With Palm-Based Oleic Acid By Electrochemical Technique

Cu(II) oleate (Cu(II)Ol) complexes were synthesized using an electrochemical technique in the presence of palm-based oleic acid as the ligand and Cu ions from the released of anode material through the electrochemical oxidation of Cu foil. The system consisted of Cu foil and a graphite rod as the anode and cathode, respectively, while ammonium acetate (CH₃COONH₄) was used as a supporting electrolyte. The optimal parameters to synthesis of Cu(II) oleate complexes from 0.1 M oleic acid are using 10 V of applied voltage in the presence of 0.5 M CH₃COONH₄ for 2 hours of electrolysis time at room temperature (∼27 degree Celsius). The results from spectroscopic studies using FTIR, XPS and UV-Vis confirms the existence of bonding between the coordinated carboxylate group of oleic acid with Cu(II) ions. This proved that the desired Cu(II) oleate complexes were successfully synthesized using electrochemical techniques. The surface morphology of the complex was analyzed using FESEM, and the micrograph obtained showed that the synthesized complexes formed thread-like structures. (author)
