Use of polymeric fullerene as a new coating for solid-phase microextraction

Abstract

The use of polymeric fullerene to coat the fiber used in solid-phase microextraction (SPME) is described. The efficiency, sensitivily, and rehabihly of the new coated fibers have been investigated for the extraction of three kinds of sample, BTEX, naphthalene congeners, and phthahc acid diesters, from the headspace of water samples. Detection limits at the ng L ] to I-tg L ] level were achieved by use of GC-FID. A wide linear range was obtained with precision lypically below 12% relative standard deviation for phthahc acid diesters. The effects on extraction efficiency of factors such as addition of salt, stirring, and exposure time were also studied.

Investigation of carbon-based nanomaterials as sorbents for headspace in-tube extraction of polycyclic aromatic hydrocarbons

“…Carbon-based nanomaterials (CNMs) have gained wide attention as sorbents in several analytical techniques, such as solidphase microextraction (SPME) fibers covered with nanomaterials [1][2][3][4], solid phase membrane tip extraction (SPMTE) [5], solid-phase extraction (SPE) [5][6][7][8][9], or as stationary phase in gas chromatography (GC) and liquid chromatography (LC) [10]. Superior material characteristics, such as high surface-to-volume ratios, high thermal stability, formation of non-covalent interactions with organic molecules, resulted in a steadily increasing application of CNM application in analytical chemistry [11].…”

Solid phase headspace microextraction of tricyclic antidepressants using a directly prepared nanocomposite consisting of graphene, CTAB and polyaniline

“…As a development in SPME fiber coatings, carbon-based nanomaterials were given attention as a potent type of coating. Diverse types of carbon based nanomaterials such as carbon nanotubes (CNTs) [16,17], fullerene [18], graphene (GN) [19] and their composites with conducting polymers [20] are utilized as SPME coatings to date.…”

A Facile Solid-Phase Micro-Extraction Fiber Based on Pine Needles Biochar Coating for Extraction of Polychlorinated Biphenyls from Water Samples

“…The lack of proper bonding of the stationary phase coating with the fiber surface seems to be responsible for relatively low thermal and mechanical stability. Diverse coating methods [22] have been applied to glue biochar to supports, among them, dip method is compatible for almost all kinds of the sorbent materials [23,24], some researchers used a thin layer of epoxy glue [25] or nafion [26] as a binder on the surface of wires.…”
