In this work, monodisperse and nano‐porous poly(bismaleimide‐co‐divinylbenzene) microspheres with large specific surface area (427.6 m 2 /g) rich pore structure were prepared by one‐pot self‐stable precipitation polymerization of 2,2′‐bis[4‐(4‐maleimidophenoxy) phenyl] propane divinylbenzene. The employed as dispersive solid‐phase extraction (DSPE) adsorbent for the triazine herbicides. Under optimized conditions, good linearities obtained between peak concentration herbicides in range 1–400 µg/L (R ≥ 0.9987) limits detection 0.12–0.31 µg/L. Triazine detected using described approach vegetable samples (i.e., cucumber, tomato, maize) recoveries 93.6%–117.3% relative standard deviations 0.4%–3.5%. addition, remained above 80.7% after being used nine DSPE cycles, showing excellent reusability microspheres. adsorption toward was a monolayer chemical adsorption. mechanism adsorbents might be combination hydrogen bonding, electrostatic interaction, π‐π conjugation. results confirmed potential use microspheres‐based coupled to high‐performance liquid chromatography method herbicide residues samples.

Emerging pollutants (EPs) encompass natural or synthetic substances in the environment that pose potential risks but have only recently been recognized monitored. EPs consist of various categories including pesticides, pharmaceuticals, hormones, mycotoxins, and endocrine disrupting chemicals (EDCs). Through several pathways, can access food, potentially leading to health impacts when their safe concentrations are exceeded. Milk, being a highly nutritious heavily consumed food product by many consumers different ages, is crucial matrix where should be regularly In literature, large number studies was dedicated for determination dairy milk, employing analytical techniques. Chromatographic based techniques were most prevalent means analysis which demonstrated significant efficiency, sensitivity accuracy this specific purpose. Prior chromatographic analysis, extraction from complex like essential. This review comprehensively covers relevant research papers on subsequent detection milk methods 2018 until 2023.

Rice is one of the crops cultivated in Malaysia, and it main diet for most population. In this study, dispersive liquid-liquid micro-extraction (DLLME) liquid chromatography-tandem mass spectrometry (LC-MS/MS) were used to develop, optimise validate a reliable, easy-to-use quick approach detect aflatoxin B1 (AFB1), B2 (AFB2), G1 (AFG1) G2 (AFG2). The extraction recoveries DLLME enhanced by addition 5% salt, utilising chloroform as solvent acetonitrile solvent. parameters - volume, salt concentration volume optimised with Box-Behnken design (BBD) response surface methodology (RSM). Under experimental conditions, excellent linearity was obtained limit detection (LOD) ranging from 0.125 0.25 ng g
