According to Lambert-Beer Law,the trace iron of tungsten alloy which had been dissolved in HF acid aqua was determined by orthophenanthroline spectrophotometry. The hydroxylamine hydrochloride was used for reductive agent. Furthermore,the wavelength of determination was 511 nm,and the pH value was 6. It was showed that the trace iron of tungsten alloy is 0. 3374%(weight percentage). The relative standard deviation is 0. 1037%. On the other hand,this method has several advantages,such as high sensitivity,less interference,rapid operation and dependable result.
