“…Procedures for bromide determination in different matrices employing potentiometry, 4,5 ion exchange chromatography, 6 capillary electrophoresis, 7 spectrophotometry [8][9][10][11] have been proposed. Generally, spectrophotometric methods present adequate sensitivity, nevertheless the time consumed to perform an analysis is very long.…”

Um procedimento automático empregando sistema de análise em fluxo para determinação de brometo em aminoácido L-alanina empregando detecção por quimiluminescência é descrito. O procedimento foi baseado na oxidação do brometo por cloramina-T seguido pela reação com lominol. Fortificando amostras com solução padrão obteve-se recuperação na faixa de 94 a 106 %. Foram obtidas características importantes tais como: resposta linear na faixa de 0,01 até 1,000 mg L ; 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.

Due to the rapid expansion in hydraulic fracturing (fracking), there is a need for robust, portable and specific water analysis techniques. Early detection of contamination is crucial for the prevention of lasting environmental damage. Bromide can potentially function as an early indicator of water contamination by fracking waste, because there is a high concentration of bromide ions in fracking wastewaters. To facilitate this, a microfluidic paper-based analytical device (μPAD) has been developed and optimized for the quantitative colorimetric detection of bromide in water using a smartphone. A paper microfluidic platform offers the advantages of inexpensive fabrication, elimination of unstable wet reagents, portability and high adaptability for widespread distribution. These features make this assay an attractive option for a new field test for on-site determination of bromide.

“…The continuous pumping of the reagents solutions is a feature due to classical FIA process [20], thus presenting as a consequence high reagent consumption and generating also large volume of waste. These disadvantages could be easily minimized employing flow manifolds based multicommutation [21,22].…”
