title: Spectrophotometric determination of bismuth with diethylenetriaminepenta-acetic acid.
abstract: Diethylenetriaminepenta-acetic acid is used for spectrophotometric determination of bismuth (at 270 nm) in 1.6 M perchloric acid. The system obeys Beer's law in the range 1-40 mug/ml. The method has been tested for the determination of bismuth in pure lead and polymetallic ores.
