“…The roughness of the structure provided by graphene and CTAB resulted in a higher surface area and more extraction efficiency of analytes in SPME approach. The SEM image of a common polyaniline fiber not containing graphene and CTAB, with a smooth surface, can be found in a report by Li [22] and Mehdinia [23].…”

“…Compared to Ref. 23, this method provides faster and simpler synthesis of composite (about 20 min compared to 24 h of the previously reported study) and requires less amounts of aniline. The extraction efficiencies of two types of graphene/polyaniline fibers (with and without the presence of CTAB) were studied (Fig.…”

We report on the direct electrochemical preparation of a nanocomposite composed of graphene, cetyl trimethylammonium bromide (CTAB), and polyaniline, and its application to headspace solid-phase microextraction (HS-SPME) of the tricyclic antidepressant drugs (TCAs) imipramine, desipramine and clomipramine. The new nanocomposite coating offers good mechanical and thermal stability and high extraction efficiency due to its large specific surface. The SPME conditions such as temperature, concentration of NaOH and extraction time were optimized with the aid of Box-Behnken design through response surface methodology. The TCAs were thermally desorbed and analyzed by GC. The limits of detections range from 0.10 to 0.35 ng mL −1 , and the calibration plots are linear within the 0.30-400 ng mL −1 concentration range. The method was successfully applied to the extraction and determination of TCAs in plasma, urine, milk and hair samples.

“…What's more, the centrifugation or filtration step which was used in traditional QuEChERS method containing GCB or C18 was omitted in the proposed method [18,19,21,22,36], so it has the advantages of simplicity and rapidity. In whole, compared to other methods for the determination of OCPs in tobacco [22], water [29,[32][33][34][35], fruit and vegetable samples [36], the method in this study has the advantages of simple to operate, low cost and high clean-up ability.…”

“…These features endow nanoporous carbons with potential for the applications for electrochemical capacitation, gas adsorption, catalysis, and sensing [7][8][9]. Moreover, some of them, such as carbon nanotubes [10,11], glassy carbon films [12], activated carbon [13], graphene [14] and fullerene [15], have already been used in SPME.…”

A nanoporous carbon derived from an aluminumbased metal-organic framework was deposited on stainless steel wires in a sol-gel matrix. The resulting fibers were applied to the solid-phase microextraction of the polycyclic aromatic hydrocarbons (PAHs) naphthalene, acenaphthene, fluorene, phenanthrene and anthracene from water and soil samples. The fiber was then directly inserted into the GC injector and the PAHs were quantified by GC-MS. The effects of salt addition, extraction temperature, extraction time, sample volume and desorption conditions on the extraction efficiency were optimized. A linear response to the analytes was observed in the 0.1 to 12 μg L −1 range for water samples, and in the 0.6 to 30 μg kg −1 for soil samples, with the correlation coefficients ranging from 0.9934 to 0.9985. The limits of detection ranged from 5.0 to 20 ng L −1 for water samples, and from 30 to 90 ng kg −1 for soil samples. The recoveries of spiked samples were between 72.4 and 108.0 %, and the precision, expressed as the relative standard deviations, is <12.8 %.
