Reed, D V

In concentrated sulfuric acid, 5-sulfosalicylic acid forms a yellow complex with titanium which is messwed spectrophotometrically at 450 m mu . The color is stable for at least 24 hours. Positive interferences from iron and vanadium are negligible provided the material contains less than 0.2% iron and 100 ppm of vanadium. Fluoride from hydrofluoric acid dissolution is reduced to a non-interfering level by fuming the sample with sulfuric acid. The interference of colored ions is corrected for through the use of a sample solution blank. The method copers the determination of 10 to 100 ppm of titamium on a one gram sample basis. (auth)
