Abstract

Cyclic voltammetry of nano-copper (II) complex (NCSu) with Cefdinir antibiotic (CFD) was studied using a glassy carbon electrode (GCE) in 0.1M KCl as a supporting electrolyte in 5% (v/v) mixed (DMF-H2O) solvent at two temperatures (298.15, 303.15 K). It was observed that copper (II) (NCSu) in nano form and Cefdinir antibiotic (CFD) form 1:1 and 1:2 ratio complexes. The complexation stability constants and Gibbs free energies of solvation were evaluated. Also the different thermodynamic parameters, enthalpies and entropies of complex formation were estimated. . The scan rate of nano-copper (II) (NCSu) in the absence and presence of cefdinir antibiotic (CFD) were studied. All mechanisms of electrode reactions were discussed and comparing the biological activities of bulk and nano- Cefdinir copper (II) complexes.
