This study's main goal was to produce a user-friendly dispersive micro solid phase extraction (dmSPE) technique with a MIL-53(Al)@BaTiO nanocomposite for the extraction and preconcentration of cadmium (Cd) in various seafood matrices, followed by using high-resolution continuum source flame atomic absorption spectrometry (HR-CS-FAAS). The MIL-53(Al)@BaTiO nanocomposite was synthesized and characterized using a range of techniques, including Fourier-transform infrared spectroscopy, field emission scanning electron microscopy, scanning transmission electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller analysis. The dmSPE technique involved the dispersion of the MIL-53(Al)@BaTiO material in the sample solution, followed by its separation from the sample matrix. The optimized method exhibited a linear range of 3.6-250 μg L, a limit of detection (LOD) of 1.2 μg L, and a preconcentration factor of 80. Two different certified reference materials were used to ensure the validation of developed method. The method was applied to different seafood samples.
本研究的主要目标是开发一种用户友好型的分散微固相萃取（dmSPE）技术，该技术采用MIL-53(Al)@BaTiO纳米复合材料，用于萃取和预富集各种海鲜基质中的镉（Cd），随后使用高分辨率连续光源火焰原子吸收光谱法（HR-CS-FAAS）进行测定。采用傅里叶变换红外光谱、场发射扫描电子显微镜、扫描透射电子显微镜、X射线衍射和布鲁诺尔-埃米特-泰勒分析等一系列技术对MIL-53(Al)@BaTiO纳米复合材料进行了合成和表征。dmSPE技术包括将MIL-53(Al)@BaTiO材料分散在样品溶液中，然后将其与样品基质分离。优化后的方法线性范围为3.6 - 250 μg/L，检测限（LOD）为1.2 μg/L，预富集因子为80。使用两种不同的有证标准物质确保所开发方法的有效性。该方法应用于不同的海鲜样品。
