Determine of stability constant of tungsten (VI) complex with histidine

Stability constant of the tungsten (VI) complex was investigated with Histidine ligand at ionic strength of 0.1 molar of NaClO and constant pH of 7.5 and 25°C with spectrophotometric method .Used wavelenght are between 250 to 265 with interval of 5nm job method was Used for determination of Stability constants. The results shows that tungsten (VI) with Histidine formed 1:1 complex (mono nuclear) at (فرمول در متن اصلی مقاله)
