Single-Channel Flow Injection Spectrophotometric Determination of Nickel Using Furildioxime in Micellar Solution
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)....

| description | 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. |
