Background
Meals components are extensively utilized in meals manufacturing for preservation, taste enhancement, and coloration enchancment. Nevertheless, their intensive use has raised issues about potential accumulation within the setting, notably in water methods. Conventional strategies for detecting these components typically lack the sensitivity wanted for hint evaluation in complicated matrices like river water.
Latest developments in materials science have launched progressive approaches, equivalent to molecularly imprinted polymers and magnetic nanoparticles, that considerably enhance the extraction and detection of goal analytes. Integrating C18 practical teams into magnetic natural polymers enhances their affinity for hydrophobic compounds, making them ultimate for extracting meals components from aqueous samples.

The synthesis course of included coating iron oxide nanoparticles with oleic acid, adopted by the incorporation of polyvinylpyrrolidone (PVP) and different reagents to create a steady polymer matrix. The ensuing composite was characterised utilizing varied strategies, together with Fourier-transform infrared spectroscopy (FTIR) and elemental evaluation, to substantiate profitable functionalization and decide the fabric’s composition.
A collection of experiments had been carried out to optimize the extraction situations and consider the nanocomposite’s efficiency. Variables equivalent to water pattern quantity, adsorbent quantity, and elution solvent had been systematically adjusted to realize the best restoration charges for the goal meals components.
The optimized technique concerned dispersing 40 mg of the C18−PS−DVB−Fe3O4 composite in 100 mL of river water, adopted by stirring to facilitate adsorption. After a specified contact time, the solid-liquid separation was carried out utilizing a magnetic area, and the adsorbed components had been eluted with a 20 mmol/L ammonium acetate resolution. The eluent was then analyzed utilizing HPLC to quantify the meals components.

The outcomes demonstrated that the C18 functionalized magnetic natural polymer nanocomposite successfully enriched the goal meals components from river water samples. Optimization experiments confirmed {that a} pattern quantity of 100 mL yielded recoveries exceeding 88.7 % for the eleven meals components examined. The tactic achieved a excessive enrichment issue of 100 occasions, indicating its potential for hint evaluation in complicated matrices. The linear vary for the detection of the meals components was established between 0.1 and 10 μg/mL, with correlation coefficients above 0.9990, showcasing the strategy’s reliability.
The boundaries of detection (LODs) and limits of quantification (LOQs) had been discovered to be between 0.6 and three.1 μg/L and a couple of.0 and 10.0 μg/L, respectively, making them appropriate for environmental monitoring. The tactic’s precision was assessed via intra-day and inter-day repeatability checks, yielding relative customary deviation (RSD) values under 5.9 % and eight.8 %, respectively. These outcomes point out that the strategy is each correct and reproducible, making it a useful software for the detection of meals components in environmental samples.
The research highlighted the importance of utilizing a magnetic solid-phase extraction (Magazine-dSPE) method, which simplifies the pattern preparation course of and enhances the effectivity of analyte restoration. Using a functionalized magnetic polymer not solely improves the selectivity for hydrophobic meals components but additionally permits for straightforward separation from the pattern matrix.
