Abstract:

In this research article, a sustainable fatty acids switchable solvent based vortex assisted liquid phase microextraction (SS-VA-LPME) method coupled with flame atomic absorption spectrometry (FAAS) was developed for the selective and accurate analysis of manganese (Mn) in food samples. Five fatty acid-SS were prepared for the selective extraction of Mn(II) ions. Microextraction conditions of the SS-VA-LPME /FAAS method were systematically optimized to maximize the extraction recovery of Mn. Under optimum conditions, linear range, limit of detection and preconcentration factor were calculated as 1–200, 0.3 ng mL−1 and 150, respectively. Also, the calibration equation of the SS-VA-LPME/FAAS method was A = 0.054 [Mn(II), ng mL−1] + 0.0026 with 0.9986 of correlation coefficient. Validation of the SS-VA-LPME/FAAS was investigated by analysis of three reference materials. The SS-VA-LPME/FAAS method was validated with good inter and intra-day precision (3.9 ≤ %), and quantitative recoveries (92.7–98.6%). The applicability of the SS-VA-LPME/FAAS method was tested by spiking food samples prepared by microwave digestion with Mn(II) solution and the recoveries were from 89 ± 8 to 98 ± 4%.
