By the spectrophotometric methods was investigated complex formation of wolfram with  2,6-ditiol-4-tret-butylphenol and hydrophobic amine (Am). As hydrophobic amins were used aniline, N-metilaniline and N,N-dimetilaniline. It was established, that mixedligand complex were formed in weak acidic medium. It was established, that relation of components corresponds W(VI):DTBF:Am =1:2:2. Maximum of light absorption observed at l=475–485 nm. Molar coefficient of light absorption was e=(2.8–3.0)×10⁴. On the base of the results was offered photometric method for determination of wolfram in steel different trade-marks. This method characterized by good reproduction (relatively standart deviation no more 0.06.) and low limit of discovery
