ABSTRACT
Flow-through stripping chronopotentiometry was used for the determination of antimony in soil samples. Antimony was deposited in potentiostatic mode on a glassy carbon porous electrode coated with Nafion® and mercury and then stripped with constant current. The accuracy of the results was confirmed by graphite furnace atomic absorption spectrometry. The LOD and LO Q were found to be 0.6 μg dm-3 and 1.7 μg dm-3, respectively. A linear response range was observed in the concentration range of 1 to 200 μg dm-3 for sample volumes of 4 ml. The repeatability and reproducibility were found to be 2.9% and 5.2%, respectively.
