Özet:

 

A pneumatic flow injection-tandem spectrometer system,  without a delivery pump, was used for the speciation of manganese  (Mn).  In this system the suction force of the pneumatic nebulizer of  a flame atomic absorption spectrometer (FAAS) was used for solution  delivery through the manifold.  Mn(VII) and total Mn (Mn(VII) and  Mn(II)) concentrations were determined using a UV-Vis spectrometer and  FAAS, respectively.  The Mn(II) concentration was determined by the  difference between the two.  The calibration curves were linear up to  15.00 mg L-1 for Mn(VII) and total Mn, with a detection limit of  0.08 mg L-1 and 0.05 mg L-1 for Mn(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 Mn(VII) and  Mn(II) in spiked and natural water, as well as industrial water.
