Abstract (EN): The development of a pre-concentration procedure based on sequential injection analysis with flame atomic absorption spectrometry (SIA/FAAS) for the determination of Mn in water samples presenting a concentration between 4.50 and 200.0 mug L-1 is described. Mn is retained on-line on a strong cationic resin (AG 50W-X8) and eluted under stopped-flow conditions with a chelating solution. Accuracy of the results attained was assessed by comparison with electro thermal atomic absorption spectrometry providing the relationship [SIA](mug/L) = 1.00 (+/-0.07)*[ETAAS](mug/L) - 0.3 (+/-7.6) after analysis of 10 samples. Evaluation of repeatability give a relative standard deviation of 2.9 and 1.8% after ten replicate of two samples containing 108 and 166 mug L-1 of Mn, respectively.
