Abstract

The complex formation of vanadium (IV) with dimercaptophenols (2,6-dimercaptophenol, 2,6- dimercapto-4-methylphenol, 2,6-dimercapto-4-ethylphenol, 2,6-dimercapto-4-tert-butylphenol) and hydrophobic amines. Heterocyclic diamines 1,10-phenanthroline, 2,2/-dipyridyl, and 4,7- diphenyl-1,10-phenanthroline were used as hydrophobic amines. The optimal conditions for the formation and extraction of mixed-ligand compounds were found, and the ratios of components in the complexes were established. Photometric methods for determining vanadium in various objects were developed. The proposed methods are characterized by good reproducibility and low detection limits.

Keywords: Vanadium; Dimercaptophenols; Hydrophobic Amines; Extraction-Photometric Method
