Resumen:
hen the interface formed between an aqueous solution containing ofloxacin, a fluorquinolone antibiotic complexed with
Fe(III), and an organic solution of a supporting electrolyte in 1,2-dichloroethane is potentiodynamically polarized, interesting
electroadsorption phenomena are observed. The narrow negative voltammetric peak observed at much lower potentials than those
corresponding to the diffusional transfer of a triply charged species, the linear response of Ip with 6, the difference in the potentials
of the positive and negative processes and the shift of this peak towards more negative potentials with sweep rate as coverage is
increased, provide clear evidence of an irreversible adsorption?desorption process displaying attractive interaction between the
adsorbate molecules at high coverage. These results are reinforced by the appearance of an important charge transfer resistance
