Simultaneous determination of antimony and bismuth by beta-correction spectrophotometry and an artificial neural network algorithm.

Simultaneous determinations of antimony and bismuth were done by beta-correction spectrophotometry and a feed forward neural network algorithm with back propagation of error. The sensitivity was improved using beta-correction spectrophotometry. The determination of trace amounts of mixtures of Sb and Bi in various matrices (river, tap and industrial… (More)
