“…Since the enrichment factor depends on the solution volume, a high solution volume provides a high enrichment factor. Too large a sample volume, however, could affect the adsorption of the amaranth onto the adsorbent, which would affect adsorption efficiency (Klongklaew et al 2020). Therefore, in order to facilitate the operation, the volume of the amaranth solution was selected to be 10 mL.…”

A buoyant solid-phase extraction adsorbent was prepared by sodium alginate-coated hollow glass microspheres (HGMs) modified with 3-aminopropyltrimethoxysilane (3-APTS) for the separation and enrichment of anionic dye amaranth. After adsorbing amaranth, these low-density adsorbents can float on the surface of the solution, so the separation between adsorbents and substrates can be carried out by flotation. Quantitative determination of amaranth after separation and enrichment can be achieved by combining spectrophotometry. Under the optimum conditions, the linear range and detection limit for amaranth detection were 0.02 mg L −1-2.0 mg L −1 and 0.0021 mg L −1 , respectively. The proposed method was applied to the determination of amaranth in different beverages, and the results were in good agreement with those by high-performance liquid chromatography (HPLC). The recoveries of amaranth in different beverages were between 97.93 and 105.91%. The floating adsorbent can be used as a conventional sample preparation method for the detection of low concentration analytes in complex samples.

“…2 However, excessive use of antibiotics may result in drug residues in food of animal origin that cannot be completely metabolized in animals' bodies. 3 Residual drugs enter the human body through the food chain and cause harmful effects to human health. Research studies have shown that antimicrobials are the most commonly detected antibiotics in surface water sources, 4 particularly fluoroquinolones, which are used to inhibit DNA gyrase in DNA replication.…”

“…Fluoroquinolone antibiotics (FQs) were developed in 1970–80s for humans and livestock. They are widely used as veterinary drugs and feed additives because of their good antibacterial activity, oral absorption, and tissue permeability [1]. However, due to the poor biodegradability of FQs, their widespread use has led to residues in animal‐derived foods.…”

By monomer‐mediated in‐situ growth synthesis strategy, with hydroquinone and 1,3,5‐tris(4‐aminophenyl)benzene as monomers, a core‐shell magnetic porous organic polymer was synthesized through a simple azo reaction. Based on this, a magnetic solid‐phase extraction–high‐performance liquid chromatography–fluorescence detection method was proposed for the analysis of fluoroquinolones in a honey sample. With ofloxacin, ciprofloxacin, enrofloxacin, lomefloxacin, and difloxacin as target analytes, factors affecting the extraction efficiency had been optimized. The LODs were 1.5–5.4 ng/L (corresponding to 0.23–0.81 μg/kg in honey). The linear range was 0.005–20 μg/L for difloxacin, 0.01–20 μg/L for ofloxacin, ciprofloxacin and lomefloxacin, and 0.02–20 μg/L for enrofloxacin. The enrichment factor was 84.4–91.7‐fold with a high extraction efficiency of 84.4–91.7%. The method was assessed by the analysis of target fluoroquinolones in honey samples, and the recoveries for the spiked samples were 79.3–95.8%. The results indicated that the established magnetic solid‐phase extraction–high‐performance liquid chromatography–fluorescence detection method is efficient for the analysis of trace fluoroquinolones in honey.
