Abstract:
Uranium (VI) (U(VI)) forms a complex with dipicolinic acid (2, 6-pyridinedicarboxylic acid).This complex can be used for a highly sensitive and selective determination of uranium by adsorptive cathodic stripping voltammetry (ACSV) using a hanging mercury drop electrode (HMDE) as working electrode. Influence of effective parameters such as pH, concentration of ligand, accumulation potential and accumulation time on the sensitivity and selectivity were studied. The detection limit (3sigma of the blank value) obtained under the optimal experimental conditions is 0.27 x 10(-9)M after 150s of the accumulation time. The peak current is proportional to the concentration of U(VI) in the range of 1 x 10(-9) to 1.2 x 10(-7)M. The relative standard deviation of 2.5% at the 3.5 x 10(-8)M level was obtained. The interference of some metal ions and anions were studied. The application of this method was tested in the determination of uranium in synthetic and natural water samples.
