title: [Catalytic fluorimetric determination of trace amount of bromine ion].
abstract: A new catalytic fluorimetric method for the determination of bromine ion based on its catalytic effect on the oxidation of fluorescein by potassium bromate in the solution of dilute sulfuric acid has been established. The detection limit for Br- is 1.94 x 10(-2) microg/25 mL. The linear range of the determination is 6.0-12.0 microg/25 mL. The method has been applied to the determination of Br- in tablet pyridostigmini bromidum sample with satisfactory results.
