Abstract

Polycyclic aromatic hydrocarbons (PAH) are a class of persistent organic pollutants released into the environment mainly through incomplete combustion processes, posing several health risks, such as carcinogenic and mutagenic risks to humans. To address the challenges of their trace level detection, a thin film solid phase microextraction (TF-SPME) tool was developed by coating a satin fiber sheet with a hybrid material of metal organic framework (MOF-199) and polydimethylsiloxane (PDMS). This hybrid combination of MOF-199, with its high surface area, porosity, π–π interactions, and PDMS, with its hydrophobic nature, enhanced the extraction of PAHs from aqueous matrices. Various parameters, including solvent profiling, extraction and desorption time, temperature variation study, ionic strength, and stirring rate, were systematically optimized. The optimized MOF/PDMS-coated TF-SPME device achieved a limit of detection (LOD) of 0.1 ng/mL, enabling sensitive quantification. A concentration-dependent calibration curve (100–900 ng/mL) was plotted for individual PAHs to facilitate the rapid quantification. The developed MOF-199/PDMS TF-SPME device demonstrated strong alignment with green analytical chemistry principles due to reduced solvent consumption, minimal waste generation, and energy efficiency. Its greenness was further validated by AGREE, GAPI, and BAGI assessment tools. This eco-friendly and efficient device shows potential for reliable monitoring of PAHs in environmental water samples to ensure ecological and public health safety.
