Abstract

An iron-based metal organic framework (Fe-MOF) constructed using terephthalic acid as an organic linker was synthesized and characterized for its implementation in a dispersive solid-phase extraction (dSPE) procedure. This strategy was combined with a flame atomic absorption spectrophotometry (FAAS) system and employed for the preconcentration and trace level detection of copper in lion's claw tea samples. Under optimal conditions, the Fe-MOF based dSPE-FAAS method achieved a limit of detection (LOD) of 2.0 μg L⁻¹ and a limit of quantification (LOQ) of 6.7 μg L⁻¹. The determination coefficient (R²) was found to be 0.9984 for the concentration range of 5.0-100 μg L⁻¹, indicating superior linearity for the developed Fe-MOF-dSPE-FAAS method. The sensitivity was enhanced by 88.2 folds. Moreover, acceptable recovery percentages at five different spiked levels within the concentration range of 7.5-75 μg L⁻¹ for the lion's claw tea sample matrix were achieved through the application of a matrix matching strategy.
