This work aim to be one of the nanotechnology applications determining V(II) ions in petroleum products, using the new 8-HQ sensor of high sensitivity over a wide range of V(II) ions up 0.15µg/L in solution, utilizing two strategies for the fast and low-cost colorimetric determination of V(II) ions, spectrophotometric and Digital Image-Based Colorimetric Analysis techniques. At the optimum conditions, the analytical characteristics of the two techniques (e.g., limit of detection and linear range) were evaluated.
We used Coker gasoline sample to determine the content V(II) analyte, the pre-detected sample of 22.0 mg/L V(II) was taken to be the basic concentration solution and the concentration of the V(II) ion before and after detection. The mother liquor of coker gasoline of 22.0 mg/L V(II) diluted with sweet Naphtha to 10, 2, 1, and 0.5 ppm solutions and detected using 15 mg of 8-HQ sensorin each case. Successive measurements were carried out using wide-range concentrations of the standard well-known solutions of analyte ions to ensure both accuracy and precision of the analyte ion detection system. Vanadium ion was detected by naked eye and determined by UV-Vis spectroscopy (Table 3), the results are shown in (Table 7).
