The mixed-ligand complexes of molybdenum(VI) with dithiolphenols (DP) {2,6-dithiol-4-methylphenol (DTMP), 2,6-dithiol-4-ethylphenol (DTEP) and 2,6-dithiol-4-tert-butylphenol (DTBP)} in the presence of hydrophobic amines have been investigated by spectrophotometric method. The condition of complexing and extraction, physical-chemical and analytical characteristics of this complex have been found. As hydrophobic amine 2(N, N-dimethylaminomethyl)-4-methylrphenol (АP 1) and 2(N, N-dimethylaminomethyl)-4-xlor-phenol (AP 2), 2 (N, N-dimethylaminomethyl)-4-brom-phenol (AP 3) were used. It has been found that mixed-ligand complex was formed in weakly acidic medium (pH 4.1-5.9). The maximum analytical signal when complexing Mo(V) is observed at 516-534 nm. The calculated molar absorption (ε max) belongs to the range (4.16-5.35) × 10 4. The Beer's law was applicable in the range of 0.3-22 µg/ml. The extraction photometric methods of the molybdenum determination were processed. The influence of diverse ions on determination of molybdenum has been studied. The proposed method was applied successfully to determine amount of molybdenum in steel and in soil.
