“…Quantification of phenol and its derivatives are mainly based on selective chromatographic techniques, i.e. gas chromatography (GC) [14, 27] and high performance liquid chromatography (HPLC) [20, 21, 28, 29]. However, direct determination is difficult to achieve due to the complex matrices and their presence at low concentration levels.…”

This work proposes an application of amine-functionalized metal-organic framework (NH2-MIL-101(Fe)) as sorbent for dispersive micro-solid phase extraction (D-μSPE) of ten priority phenolic pollutants. The sorbent was simply synthesized under facile condition. The entire D-μSPE process was optimized by studying the effect of experimental parameters affecting the extraction recovery of the target analytes. The final extract was analyzed using high performance liquid chromatography with photodiode array detector. Under the optimum condition, the proposed procedure can be applied for wide linear calibration ranges between 1.25–5000 μg L−1 with the correlation coefficients of greater than 0.9900. The limits of detection (LODs) and limits of quantitation (LOQs) were in the ranges of 0.4–9.5 μg L−1 and 1.25–30 μg L−1, respectively. The precision evaluated in terms of the relative standard deviations (RSDs) of the intra- and inter-day determinations of the phenol compounds at their LOQ concentrations were below 13.9% and 12.2%, respectively. High enrichment factors up to 120 were reached. The developed method has been successfully applied to determine phenol residues in environmental water samples. The satisfactory recoveries obtained by spiking phenol standards at two different concentrations (near LOQs and 5 times as high as LOQs) ranged from 68.4–114.4%. The results demonstrate that the NH2-MIL-101(Fe) material is promising sorbent in the D-μSPE of phenolic pollutants.

“…As a “monolithic material”, NFMs can be used directly, which effectively avoids the “channeling effect” that exists in the particle form materials. Studies together with our previous works − have also indicated that nanofiber mats (NFMs) based SPE has a superior extraction efficiency with only a few milligrams (mg) of adsorbent and a few hundred microliters (μL) of organic solvents consumption. The sample amount required for testing has also been greatly reduced.…”

We herein describe a high-throughput 96-well plate micro-solid phase extraction sample preparation technique based on novel sulfonated-polyaniline/polyacrylonitrile nanofiber mats (sulfonated-PANI/PAN NFMs) for multiresidue detection of fluoroquinolones (FQs) in various animal-origin food samples. Through the double-modification of polyaniline and sulfonic acid, the resulting functionalized sulfonated-PANI/PAN NFMs present high extraction efficiency for FQs. Compared with the existing methods, this approach demonstrates its advantages of being suitable for more sample matrices (milk, animal muscle, liver, kidney, and egg), lower sample amount (0.5 g), lower sorbent requirement (5.0 mg), lower volume of organic solvent (0.7 mL), shorter time (0.2 min per sample), and high sensitivity (0.012−0.06 μg•kg −1 ). In addition, sulfonated-PANI/ PAN NFMs possess excellent reusability which could be reused 10 times without an obvious decrease in extraction efficiency. Combined with ultra performance liquid chromatography-tandem mass spectrometry, the novel sample preparation technique can be expected as an efficient method for routine trace FQ residue monitoring in animal-origin food samples.

“…However, post modification of these spun nanofibers to enhance functionality properties with high nitrogen containing compounds is limited. This process has proven to greatly enhance adsorption performance for different persistent environmental pollutants [39,40]. Polyaniline (PANI) is a widely used conducting and electroactive polymer due to its cost-effective synthesis via either simple chemical or electrochemical oxidation [41,42].…”
