EXTRACTION-PHOTOMETRIC DETERMINATION OF TITANIUM WITH 2,6-DITHIOL-4-TERT-BUTYLPHENOL AND HYDROPHOBIC AMINES

Abstract

This work is dedicated to the spectrophotometric study of different ligand complexes (DLC) of titanium with 2,6-dithiol-4-tert-butylphenol (DTBP) and hydrophobic amines (Am), as well as the study of their spectrophotometric characteristics. DTBP with titanium forms a colored complex, insoluble in non-polar organic solvents. Experiments on electromigration in a U-shaped tube and anion exchange on the EDE-10 P anion exchanger showed the anionic nature of the homogeneous ligand complex. When introducing hydrophobic amines into the system, the extraction of the anionic complex into the organic phase is observed in the form of DLC. Aniline, N-methylaniline, N,N-dimethylaniline are used from hydrophobic Am.
