A multicommutated flow system was developed for the determination of aluminum in crystallized fruit samples. Spectrophotometric determination is based on the reaction of aluminum with chrome azurol S. The binary sampling technique was implemented to improve mixing conditions and to minimize reagent consumption. Three different working zones were established (0.5-5.0, 5.0-25.0, and 10.0-100 ppm) using the zone sampling approach, allowing us to adapt the extent of the in-line dilution. The… CONTINUE READING
