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 microg mL(-1) and 25 microg mL(-1) with detection limits of 0.09 microg mL(-1) and 0.07 microg mL(-1) for Fe(III) and Fe(II), respectively. The mid-range precision and accuracy were &lt;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.
