Determination of bismuth by forced-flow liquid chromatography.
Bismuth(III) is retained on a cation-exchange column from dilute acid and is then separated from most other metal ions by elution with 0.5M hydrobromic acid. The elution curve can be measured spectrophotometrically and automatically recorded. This separation method is rapid and is selective for bismuth.
