Resumo (PT): multicommutated flow system using an opened-loop configuration and incorporating micropump propulsion was developed and applied in the determination of highly concentrated species in wastewater samples. The developed flow system enabled a suitable dilution level to be attained and continuously monitoring of the analytical process. A synergetic effect was also obtained with the continuous removal of the dispersed front and trailing zones of the sample plug. The developed strategy was evaluated on the determination of iron in high concentrated wastewater samples without any pre-treatment. The continuous sample recirculation permitted an increase in linear range up to 10 g · l-1. <br> <br> Keywords: Multicommutation; micropump; open-loop; flow analysis; total iron <br> <a target="_blank" href="http://www.informaworld.com/smpp/content~db=all~content=a780376960"> Texto integral </a> <br> <br>
