Abstract;A pneumatic flow injection-tandem spectrometer system, without a delivery pump was used for the speciation of iron. In this system, the suction force of a pneumatic nebulizer of a flame absorption spectrometer was used for solution delivery through the manifold. The Fe(III) and total Fe concentrations were determined using thiocyanate ion in a UV-Vis spectrometer and a FAAS, respectively. The Fe(II) was determined by the difference. The calibration curves were linear up to 18 .MU.g mL'-1' and 25 .MU.g mL'-1' with detection limits of 0.09 .MU.g mL'-1' and 0.07 .MU.g mL'-1' for Fe(III) and Fe(II), respectively. The mid-range precision and accuracy were <2.5% and .+-.3% for the two species, respectively, at a sampling rate of 120 h'-1'. This system was applied for the determination of Fe(III) and Fe(II) in industrial water, natural water and spiked samples. (author abst.)
