A zinc mixed-ligand microporous metal-organic framework as solid-phase microextraction coating for priority polycyclic aromatic hydrocarbons from water samples

摘要

For the first time, a novel triple catenated Zn2+-pillared metal-organic framework (PUM 210) is proposed as solid-phase microextraction coating for the extraction of 16 priority pollutant polycyclic aromatic hydrocarbons (PAHs) from water samples and their subsequent quantitation via gas chromatography-mass spectrometry. Extraction was optimized by using a central composite face centered design followed by the multicriteria method of the desirability functions. The best conditions for the extraction of the sixteen analytes were found in correspondence to an extraction temperature of 30 degrees C and an extraction time of 30 min.
