摘要：
The complexation of molybdenum(VI) with Bromopyrogallol Red in the presence of the nonionic surfactant Triton X-114 is studied spectrophotometrically. A mixed-ligand complex is formed with the component ratio 1: 1: 1 and a stability constant of logβ = 8.2. The effect of pH, time, temperature, and component concentrations on the formation of the mixed-ligand complex is studied. A highly selective procedure for the spectrophotometric determination of trace molybdenum(VI) in drinking water in the presence of tungsten has been developed.
