“…Recently, an advanced form of SPE, dispersive solid‐phase extraction (d‐SPE), has been developed; in this technique the micro (or nano) amount of adsorbent is directly dispersed into the sample solution containing the target analytes, after extraction time, the adsorbent containing analytes is separated by centrifugation . Various materials have been used as a sorbent such as carbon materials , silica , zeolite , and various polymers .…”

Chitosan-grafted polyaniline was synthesized and applied as a sorbent for the preconcentration of phthalate esters in dispersive solid-phase extraction. By coupling dispersive solid-phase extraction with high-performance liquid chromatography and response surface methodology (central composite design), a reliable, sensitive, and cost-effective method for simultaneous determination of phthalate esters including dimethyl phthalate, di-n-butyl phthalate, and di(2-ethylhexyl)phthalate was developed. The morphology of sorbent had been studied by scanning electron microscopy and its chemical structure confirmed by Fourier transform infrared spectroscopy. Under optimum condition, good linearity was observed in the range of 5.0-5000.0 ng/mL. The limits of detection (S/N = 3) and limits of quantification (S/N = 10) were 0.1-0.3 and 0.3-1 ng/mL, respectively. The relative standard deviations were less than 8.8%. Finally, this procedure was employed for extraction of trace amounts of phthalic acid esters in milk samples, the relative recoveries ranged from 82 to 103%.

“…Sulfonamides have been extracted from milk samples by GO/Fe 3 O 4 sorbent prior to their determination by HPLC-MS/MS [53] or capillary electrophoresis-diode array detection (CE-DAD) [54]. Sulfadiazine has been extracted from milk, honey and water samples with GO/Fe 3 O 4 prior to its spectrophotometric and optimized angle mode-mismatched thermal lens spectrometric determination (OAMTLS) [55].…”

Magnetic Solid-Phase Extraction of Organic Compounds Based on Graphene Oxide Nanocomposites

et al. 2020

Graphene oxide (GO) is a chemical compound with a form similar to graphene that consists of one-atom-thick two-dimensional layers of sp2-bonded carbon. Graphene oxide exhibits high hydrophilicity and dispersibility. Thus, it is difficult to be separated from aqueous solutions. Therefore, functionalization with magnetic nanoparticles is performed in order to prepare a magnetic GO nanocomposite that combines the sufficient adsorption capacity of graphene oxide and the convenience of magnetic separation. Moreover, the magnetic material can be further functionalized with different groups to prevent aggregation and extends its potential application. Until today, a plethora of magnetic GO hybrid materials have been synthesized and successfully employed for the magnetic solid-phase extraction of organic compounds from environmental, agricultural, biological, and food samples. The developed GO nanocomposites exhibit satisfactory stability in aqueous solutions, as well as sufficient surface area. Thus, they are considered as an alternative to conventional sorbents by enriching the analytical toolbox for the analysis of trace organic compounds.

“…To be free from these problems and maintain the advantageous properties, G and GO sheets were bound covalently to silica. [23][24][25][26] Chlorophenols (CPs) are important pollutants that are ubiquitous in environmental water and soil. 27 Because of their high toxicity and potential carcinogenicity, some of them, such as 4-chlorophenol (4-CP), 2,4-dichlorophenol (2,4-DCP), and 2,4,6-trichlorophenol (2,4,6-TCP), have been included as pollutants in the USA.…”

A novel deep eutectic solvent (DES) and ionic liquid (IL)‐modified graphene (G) and graphene oxide (GO) were synthesized and used as effective adsorbents for the preconcentration of three chlorophenols (CPs), 4‐chlorophenol (4‐CP), 2,4‐dichlorophenol (2,4‐DCP), and 2,4,6‐trichlorophenol (2,4,6‐TCP), in environmental water samples prior to high‐performance liquid chromatography (HPLC). The new materials were characterized by scanning electron microscopy (S‐4200) and Fourier‐transform infrared spectrometry. The prepared functionalized GO@silica shows remarkable adsorption capacity toward CPs. When used as solid‐phase extraction (SPE) sorbents, a superior recovery (88.49–89.70%) could be obtained compared to commercial sorbents, such as silica and aminosilica. Based on this, a method for the analysis of CPs in water samples was established by coupling SPE with HPLC. These results highlight the potential new role of DES and IL‐modified GO in the preparation of analytical samples.
