Özet

A micro-solid-phase extraction (μSPE) method has been proposed for the separation-preconcentration of lead on MXene (Ti3C2), prior to its high-resolution continuum source flame atomic absorption spectrometry (HR-CS-FAAS) detection. MXene was produced and characterized with a variety of methods, including Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), scanning transmission electron microscopy (STEM), and X-ray diffraction. To optimize a variety of factors, including pH, eluent type, MXene quantity, and contact duration "one-factor-at-a-time" method was used. The MX-μSPE process included dispersing the MXene in the sample solution and then separating it from the matrix. The improved technique has limit of detection (LOD) of 0.5 µg L−1, and a preconcentration factor of 20. Two different certified reference materials were used to verify the accuracy of the proposed procedure. The procedure was applied to determination of lead contents of water and tobacco samples.
