خلاصه مقاله: An electrospun composite base polyacrylonitrile/iron (III)/Mg-based metal-organic framework 88B (PAN/ Fe/Mg-MIL-88B)....

An electrospun composite base polyacrylonitrile/iron (III)/Mg-based metal-organic framework 88B (PAN/ Fe/Mg-MIL-88B) was prepared and utilized as a viable sorbent for the determination of phthalate esters in mineral water samples, as well as urine, plasma and blood; applying spin column micro solid-phase extraction (SC-μSPE) method. The synthesize of the electrospun nanofibers was surveyed using energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction analysis while the morphology of composites was studied by field emission scanning electron microscopy. The introduction of Fe/Mg-MIL-88B into the polymer matrix significantly enhances the extraction efficiency of the prepared sorbent as a result of providing hydrophobic, hydrogen bonding, and π-π interactions with the target analytes. The effects of sorbent amount, type and volume of desorption solvent, number of cycles and centrifugation speed of both adsorption and desorption steps were optimized.
