Abstract
Bismuth (0-20 mu g ml(-1)) can be determined spectrophotometrically at 485 nm after its adsorptive extraction from dilute sulfuric acid solution as te trabutylammonium tetraiodobismuthate(III) on microcrystalline benzophenone followed by dissolution of the solid phase in ethyl acetate, The effects of reaction conditions, diverse ions and masking studies are reported, The sy stem has been applied to the determination of bismuth in pharmaceutical sam ples.
