Abstract

This study presents an efficient and straightforward approach for the easy synthesis and innovative analytical application of an industrial nanomaterial of BaSrTiO₃ (BST). Characterization techniques including XRD (X-ray Diffraction), FTIR (Fourier transform infrared spectroscopy), and SEM (scanning electron microscopy) were utilized for characterizing the synthesized nanomaterial. Subsequently, the incorporation of BaSrTiO₃ nanomaterial-based DSPME (dispersive solid phase microextraction) and FAAS (flame atomic absorption spectrophotometry) was implemented for the preconcentration of Cd with enhanced precision and accuracy. Each variable influencing the outcome of extraction efficiency has been defined in the optimization studies. The limit of quantification (LOQ) and limit of detection (LOD) values for the BaSrTiO₃ (BST)-DSPME-FAAS system were determined to be 1.1 µg/L and 0.33 µg/L, respectively. Recovery examinations were conducted on two different thyme tea samples utilizing multiple calibration methodologies. The calculated percent recovery values from the spiked samples were in the range of 89.2-123%.

基于BaSrTiO3纳米材料的分散固相微萃取火焰原子吸收法测定百里香样品中的镉。

本研究为工业纳米材料BaSrTiO3 （BST）的简单合成和创新分析应用提供了一种高效、直接的方法。利用XRD （x射线衍射）、FTIR（傅里叶变换红外光谱）和SEM（扫描电子显微镜）等表征技术对合成的纳米材料进行了表征。随后，采用基于BaSrTiO3纳米材料的分散固相微萃取（DSPME）和火焰原子吸收分光光度法（FAAS）进行Cd的预富集，提高了Cd的精密度和准确度。在优化研究中，确定了影响提取效率结果的各个变量。测定BaSrTiO3 (BST)-DSPME-FAAS体系的定量限（LOQ）和检出限（LOD）分别为1.1µg/L和0.33µg/L。利用多种校准方法对两种不同的百里香茶样品进行了回收率检验。加标样品的回收率为89.2 ~ 123%。
