A novel solid-phase extraction method for separation and preconcentration of Nickel(II) in hydrogenated vegetable oils using Sudan III functionalized Fe3O4
This study presents a novel approach for separation/preconcentration of Ni(II) from hydrogenated vegetable oils prior to FAAS detection. Sudan III modified Fe3O4 that was characterized by FTIR and SEM, was utilized as solid phase extractor. Critical parameters effective on sorption and elution of Ni(II) were optimized using central composite design. The optimum conditions were 58.3 s vortexing time, 0.22 g sorbent mass and 19.1 mL sample volume for sorption and 6 mL of 0.86 mol L−1 HNO3 with 95 s vortexing time for elution. LOD and LOQ of the method were 35.9 μg kg−1 and 119.6 μg kg−1, respectively. Preconcentration factor was obtained as 3.2 and sample frequency was 23.4 h−1. Organometallic Ni standard was used in validation and recovery was 97 ± 4 % with 4.1 % precision. Applicability was proved by the analysis of commercial hydrogenated vegetable oils with recoveries between 93.0 and 108.6 %. Environmental sustainability was assessed using the Analytical GREENness calculator, resulting in a greenness score of 0.51. This method offers a sensitive, efficient, and eco-friendly approach for trace Ni(II) analysis in complex oily matrixes.
期刊介绍:
Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome.
Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
