Abstract

The complexation of Cu(II) with dimercaptophenols (2,6-dimercapto-4-isopropylphenol and 2,6-dimercapto-4-sec-butylphenol) and hydrophobic amines has been investigated by instrumental methods. Heterocyclic diamines such as 1,10-phenanthroline, 2,2'-dipyridyl and 4,7-diphenyl-1,10-phenanthroline (bathophenanthroline) were used as hydrophobic amine. The optimal conditions for the formation and extraction of mixed-ligand compounds were found and the ratios of components in the complexes were established. Spectrophotometric techniques for the determination of Cu(II) in various objects have been developed. The proposed methods are characterized by good reproducibility and low detection limits.
