摘要：

Spectrophotometric determination of tungsten by the reaction with phenylfluorone and benzyldodecyldimethylammonium bromide has been elaborated. In the 0.1 mol l(-1) HCl the complex shows the absorption maximum at 515 nm. Molar absorptivity is 1.30.10(5). Tungsten can be determined in the range 0.02-0.28 mg.ml(-1).
