Abstract EN
A very simple, selective, and fast flow injection spectrophotometeric method is developed for determination of nickel using furildioxime as complexing agent.
Micellar solution of brij-35 is employed to solubilize the sparingly soluble complex of Ni-furildioxime in buffered aqueous system (pH-9.00).
Under optimized conditions, absorbance is linear from 0.02 to 10 μg mL-1 using 500 μL sample volume and from 10 to 30 μg mL-1 using 50 μL sample volume of nickel at 480 nm, with R2= 0.9971 and 0.9916, respectively.
The molar absorption coefficient and Sandell's sensitivity were 6.0×103 L mol-1 cm-1 and 0.01 ng cm-2, respectively.
The sample throughput of the method is 120 samples per hour with RSD of 0.01–0.2% for 0.02 to 10 μg mL-1 nickel (n=5), indicating that the method is highly precise and reproducible.
Interference from cobalt is removed by Nitroso R-salt-modified XAD-16.
The developed method is validated by analysing certified reference materials and is applied to assess nickel content of commercially available cigarettes.
