Abstract: The complexation of tungsten (VI) with 2-hydroxy-5-chlorothiophenol in the presence of diphenylguanidine is studied by spectrophotometry. Optimal conditions for the formation and extraction of the complex are determined. It is found that a mixed-ligand complex is formed at pH 5–6. Chloroform and dichloroethane are the best extractants. Some physicochemical characteristics of the mixed-ligand complex are determined; the molar absorption coefficient at 480 nm is 5.6 × 104. The molar ratio of components in the complex is 1: 2: 2.
