Abstract: Mixed-ligand complexes of Tantalum (V) with dithiolphenol (DP) {2, 6-dithiolphenol (DTP) and its derivatives (2, 6-dithiol-4-methylphenol (DTMP), 2, 6-dithiol-4-ethylphenol (DTEP), 2, 6-dithiol-4-propylphenol (DTPP), 2, 6-dithiol-4-tert-buthylphenol (DTBP)} in the presence of hydrophobic amines (Am) have been studied by spectrophotometry. As hydrophobic amine were used aniline (An), N-methylaniline (MAn), N, N-dimethylaniline (DAn), aminopyridine (APy), dipyridyl (DiPy), diphenylguanidine (DPG), and triphenylguanidine (TPG). The best organic solvent was chloroform. Extraction of mixed ligand complexes is maximal at pH 2.9-6.0. The optimal conditions for the formation and extraction of mixed-ligand compounds have been found and the ratios of components I the complexes have been determined. The Beer’s law was applicable in the range of 0.03-3,8μg/ml. The method is free from common interferences. A procedure has been developed for extraction – spectrophotometric determination Tantalum in steel.
