Abstract
Abstract
In this study, a simple and rapid dispersive liquid–liquid
microextraction (DLLME) was developed for the determination of
uranium in water samples prior to high performance liquid
chromatography with diode array
detection. 1-(2-pyridylazo)-2-naphthol (PAN) was used as
complexing agent. The effect of various parameters on the
extraction step including type and volume of extraction and
dispersive solvents, pH of solution, concentration of PAN,
extraction time, sample volume and ionic strength were studied and
optimized. Under the optimum conditions, the limit of detection
(LOD) and preconcentration factor were
0.3 μg L−1 and 194,
respectively. Furthermore, the relative standard deviation of the
ten replicate was <2.6%. The developed procedure was then
applied to the extraction and determination of uranium in the
water samples.
