Abstract :A pneumatic flow injection-tandem spectrometer system, without a delivery pump, was used for the speciation of manganese insert ignore into journalissuearticles values(Mn);. In this system the suction force of the pneumatic nebulizer of a flame atomic absorption spectrometer insert ignore into journalissuearticles values(FAAS); was used for solution delivery through the manifold. Mninsert ignore into journalissuearticles values(VII); and total Mn insert ignore into journalissuearticles values(Mninsert ignore into journalissuearticles values(VII); and Mninsert ignore into journalissuearticles values(II);); concentrations were determined using a UV-Vis spectrometer and FAAS, respectively. The Mninsert ignore into journalissuearticles values(II); concentration was determined by the difference between the two. The calibration curves were linear up to 15.00 mg L-1 for Mninsert ignore into journalissuearticles values(VII); and total Mn, with a detection limit of 0.08 mg L-1 and 0.05 mg L-1 for Mninsert ignore into journalissuearticles values(VII); and Mn, respectively. The mid-range precision and accuracy were < 1.89% and \pm 2.50% for the 2 species, respectively, at a sampling rate of 80 samplings h-1. This system was used for the determination of Mninsert ignore into journalissuearticles values(VII); and Mninsert ignore into journalissuearticles values(II); in spiked and natural water, as well as industrial water.
