Resumo: An automatic flow analysis procedure for bromide determination in L-alanine aminoacid employing detection by chemiluminescence is described. The procedure was based on the bromide oxidation by chloramine-T followed by reaction with luminol. Spiking sample with standard solution gave recoveries values ranging from 94 to 106 %. Profitable features such as linear response ranging from 0.01 to 1.000 mg L-1 bromide (R = 0.999); detection limit of 8.9 µg L-1 Br-; relative standard deviation of 3.0% (n = 10); sampling throughput of 18 determination per hour; and reagent consumption 0.07 mg luminol and 0.4 mg chloramine-T per determination were achieved.
