| Abstract | ||||
| The redox behavior of uranyl zinc acetate (UZAc) alone and in the presence of 4-Fluoro benzoic acid (FBA) was studied in 0.1 M HCl as supporting electrolyte. The cyclic voltammograms gave a reversible redox couple for the transfer of U (VI) to U (IV). Zn ion gave waves out of our discussion range. Complex is formed by the interaction of UZAc, with 4-Fluoro benzoic acid was formed. The thermodynamic Gibbs free energies and stability constant for the interaction of uranyl zinc acetate with 4-Flouro benzoic acid were estimated and their values were discussed. | ||||
