“…The application of d-SPME and d-SPE graphene-based sorbents is also a trend in food and water analysis. For example, the d-SPE phase composed of magnetic graphene oxide (GO) tert-butylamine (TBA) fixed in the magnetic particles’ (GO/Fe 3 O 4 /TBA) nanocomposite was successfully applied in the determination of herbicides in vegetables and water samples [ 48 ]. The GO/Fe 3 O 4 /TBA sorbent was prepared by co-precipitating GO and Fe 3 O 4 particles.…”

This review provides an overview of recent advancements in applying graphene-based materials as sorbents for liquid chromatography (LC) analysis. Graphene-based materials are promising for analytical chemistry, including applications as sorbents in liquid chromatography. These sorbents can be functionalized to produce unique extraction or stationary phases. Additionally, graphene-based sorbents can be supported in various materials and have consequently been applied to produce various devices for sample preparation. Graphene-based sorbents are employed in diverse applications, including food and environmental LC analysis. This review summarizes the application of graphene-based materials in food and environmental water analysis in the last five years (2019 to 2023). Offline and online sample preparation methods, such as dispersive solid phase microextraction, stir bar sorptive extraction, pipette tip solid phase extraction, in-tube solid-phase microextraction, and others, are reviewed. The review also summarizes the application of the columns produced with graphene-based materials in separating food and water components and contaminants. Graphene-based materials have been reported as stationary phases for LC columns. Graphene-based stationary phases have been reported in packed, monolithic, and open tubular columns and have been used in LC and capillary electrochromatography modes.

“…Phase transfer (adsorption and partition) is the typical method for extraction and preconcentration of target analytes in a complex sample matrix [29]. So far, to realize these transfers, some sample preparation techniques have been used for extraction (separation) and/or preconcentration of PGRs, including liquid-liquid extraction (LLE) [30][31][32], SPE [33], SPME [34], magnetic SPE (MSPE) [35], dispersive SPE (DSPE) [36], dispersive micro-SPE [37], pipette tip SPE (PT-SPE) [38], matrix solid-phase dispersion [39], and other emerging sample preparation methods [40].…”

Plant growth regulators are a class of physiologically active substances that could modify or regulate basic physiological processes in the plant and defense against abiotic and biotic stresses, including natural plant growth regulators and synthetic ones. Different from natural plant growth regulators with low content and high cost of extraction in plants, synthetic ones can be produced in large‐scale production and widely used in agriculture for increasing and securing yield and quality of the harvested produce. However, like pesticides, the abuse of plant growth regulators will have negative impacts on human beings. Therefore, it is important to monitor plant growth regulators residues. Due to the low concentration of plant growth regulators and complex matrices of food, it is necessary to isolate and extract plant growth regulators by appropriate adsorbents in sample preparation for obtaining satisfactory results. In the last decade, several advanced materials as adsorbents have shown superiority in sample preparation. This review briefly introduces the recent application and progress of advanced materials as adsorbents in sample preparation for extraction of plant growth regulators from the complex matrix. In the end, the challenge and outlook about the extraction of plant growth regulators of these advanced adsorbents in sample preparation are presented.

ABSTRACT. The purpose of this study was to develop a method for the extraction and determination of 2,4-dichlorophenoxyacetic acid (2,4-D) from the soil, sediment, and water, and to investigate its stability in water using high-performance liquid chromatography (HPLC). The recoveries of the spiked compound from water and soil samples was found to be in the range of 80 to 100%. The yield of 2,4-D during acidification of the corresponding amine was 93.84-99.98%. A calibration curve for the method showed good linearity (R2 ≥ 0.9996). The LOD was determined to be 0.45 µg/mL while the LOQ was 2 µg/mL. From the analysis of the samples, 2,4-D was not detected in sediment or soil samples from the Wafiko or Kontola sites (Ethiopia), respectively. The 2,4-D concentrations in soil samples from Bochessa, and water samples from Wafiko and Sher sites (Ethiopia) were high, ranging from 68.22 to 167.7 mg/L which exceeded the United States Environmental Protection Agency (US EPA) regulatory agency standards of 70 µg/L. A 45-day experiment on spiked water samples from Lake Koka (Ethiopia) demonstrated that the acidic form of 2,4-D is stable in water with 73.46 ± 2.00% recoveries. The developed method can be used to determine 2,4-D residues in soil, sediment, and water. KEY WORDS: 2,4-Dichlorophenoxyacetic acid, Lake Koka, Sediment, Soil, Stability, Water Bull. Chem. Soc.
