Ion-pair sorptive extraction of perfluorinated compounds from water with low-cost polymeric materials: Polyethersulfone vs polydimethylsiloxane

Enrichment of perfluorinated alkyl substances on polyethersulfone using 1-methylpyperidine as ion-pair reagent for the clean-up of carrot and amended soil extracts

“…33%) for the long chain PFCAs (PFNA and PFDA), short chain PFCAs showed a higher affinity for the aqueous media. The same trend was observed by Villaverde-de-Saá et al [44] during the preconcentration of water samples.…”

“…Alzaga and Bayona [37] and Villaverde-de-Saá et al [44] employed TBA as ion-pair reagent to preconcentrate PFASs in aqueous matrices and improved the solid phase micro extraction (SPME) and solid (polymeric material) liquid extraction extractability. Regarding the polymeric material, PES was firstly proved as a good alternative for the extraction of polar analytes [45] and, later, for PFASs in water samples [44]. However, in the present work, the purpose was not the mere preconcentration but to find an alternative clean-up step for FUSLE extracts of solid samples.…”

Microextraction with polyethersulfone for bisphenol-A, alkylphenols and hormones determination in water samples by means of gas chromatography–mass spectrometry and liquid chromatography–tandem mass spectrometry analysis

“…One of the most used strategies for the determination of trace organic compounds in liquid matrices is centered on the miniaturization and automation of sample preparation techniques [11][12][13][14][15]. In addition to the well-established microextraction techniques, mainly solid phase microextraction (SPME) [11,[16][17][18] and stir bar sorptive extraction (SBSE) [19][20][21][22][23][24][25][26][27], polyethersulfone (PES) polymer has emerged recently [14,28,29] as a very suitable choice for the extraction of polar species, improving significantly the extraction efficiencies provided by other polymeric materials such as polydimethylsiloxane (PDMS), among others.…”
