Mixed-ligand complexes of Vanadium (IV, V) with 2,6-dithiol-4-methylphenol (DTMP) and hydrofobamins(Am) have been studied by spectrophotometry. Extraction of mixed ligand complexes is maximal at pH 3.8-5.3. 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 0.04-3.6mg/ml.The method is free from common interferences. A procedure has been developed for extraction – spectro-photometric determination vanadium in soils andin oil and oil-products.
