By the methods spectrophotometric methods was investigated complex formation of wolfram(VI) with  2-hydroxy-5-bromthiophenol (HBTF)  and aminophenols (AF). It was established, that mixedligand complex were  formed in weak acidic medium. It was established, that relation of components corresponds W(V):HBTF:AF-=1:2:2. Maksimum of light absorption observed at l=460–470 nm. Molar coefficient of light absorption was e=(2.4–2.6)·10⁴. On the base of the results was offered photometric method for determination of wolfram in steel different trade-marks
