“…Nowadays, researchers are focusing on fabricating composite nanofibers which exhibit specific functional properties for solid phase extraction (SPE) application [1][2][3][4][5]. Chitosan, as the second abundance of natural polysaccharide, is obtained from chitin and is well known for its biocompatible, nontoxic and biodegradable properties [6].…”

“…To increase the adsorption of different compounds on electrospun nanofibers, the following methods have been attracted the most attention: (1) increasing the surface area of nanofibers, (2) surface modification of nanofibers with functional groups and (3) fabricating of composite nanofibers [1,[16][17][18]. Composite nanofibers modified by the functional groups have been extensively used because of their specific properties such as: (1) high surface-to-volume ratio,…”

The nanofibers of biocompatible Chitosan/MIL-101 (Fe) composite were synthesized by a simple, cheap and accessible electrospining method and applied for mat-based extraction of trace amount of Δ9-tetrahydrocannabinol (THC) from human whole blood sample following its combination by high performance liquid chromatography-ultraviolet detection. The composite nanofibres were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction and N adsorption-desorption experiments. The volume of eluting solvent, sorbent amount, pH and% NaCl (w/v) influencing on the responses were investigated using factorial experimental design. The optimum point was achieved by analysis of the results according to design expert (DX) software. The volume of eluting solvent, sorbent amount and pH were significant variables, and 150μL, 7mg and 7.0 were respectively chosen for obtaining the best extraction response. Under the optimum conditions, the method was exhibited a linear range of 0.1-100μgL (R=0.9943) for THC with a detection limit of 0.04μgL. Acceptable values for intra-day (3.2%) and inter-day (4.8%) relative standard deviations were obtained. The high preconcentration factor (970) and satisfactory recoveries (88.2%-92.4%) in whole blood samples were achieved which proved the capability of the method for trace determination of THC in the human whole blood samples.

“…This change in geometry can practically increase the extraction recovery of analytes without sacrificing the analysis time due to the large extraction phase surface area-to-volume ratio of the adsorption thin-films. 15,16 Some reported applications of TFME have been published in different matrixes, such as biological matrixes, 17 water, 15,[18][19][20][21] indoor air, 22 human exhaled breath condensates 23 and wine. 24 Filter paper, as 100% naturally derived cellulose nanofibers with a surface area of larger than 100 m 2 /g, 25 has been used as a platform in analytical and clinical chemistry because it is affordable, sustainable, hydrophilic, inert, and stable over a broad range of pH/ionic strengths.…”

Based on the tunability of ionic liquids (ILs) according to the specific requirement of an application, 1-dodecylimidazolium chloride with amphiphilic structures was chemically fabricated on the surface of filter papers (DIL-FPs) for the first time. After synthesis, DIL-FPs was characterized by scanning electronic microscopy, energy dispersive X-ray spectroscopy and Fourier-transform infrared spectroscopy. DIL-FPs was used as a novel thin-film microextraction (TFME) phase for the preconcentration of amphiphilic bisphenol A from plant oil samples. The related extraction variables were studied in a spiked sunflower seed oil. Under the optimal conditions, the linear range was 5.0 -1000 μg L -1 with a correlation coefficient of 0.9976. The limit of detection (S/N = 3) and the enrichment factor of the proposed method were 2.7 μg L -1 and 118, respectively. The intra-day precision and inter-day precision for six repeated determinations were 2.3 and 4.9%, respectively. These plant oil samples used in this work were free of bisphenol A contaminations. The recovery study carried out in different plant oil samples and mean recoveries ranged from 77.16 to 97.10%. The developed DIL-FPs extraction film phase followed by HPLC-UV provides a potential pretreatment strategy for the analysis of weak organic acid compounds in plant oil samples.
