The complexation reactions between iodoquinol and Co2+, Mn2+, Cd2+, Pb2+ and Zn2+ cations were studied in different DMF/EtOH binary mixtures at the ionic strength of 0.1 M sodium nitrate. The spectrophotometric method was used for the determination of stability constants and stoichiometries of complexes. Job’s and moleratio methods evidenced a 1:1 stoichiometry in all of the cases. It was found that the stability constants of the complex formed between the ligand (IQ) and the cations in all cases in crease with in creasing of EtOH per cent in binary mixtures. In the most cases the maximum formation constant for Zn2+–IQ complex was found.
