“…When the ACN concentration was 98%, the adsorption rates were almost 100%, with no targets detected in the washing solvent. This is a typical phenomenon in HILIC 26 . To completely trap carbadox and olaquindox on the ATP@Fe 3 O 4 @poly(VBSIm‐AM‐MBA) particles, 98% ACN was used as the washing solvent in the subsequent experiments.…”

BACKGROUND Carbadox and olaquindox have been banned from feeds since 1998 by the EU because of their mutagenic, photoallergic, and carcinogenic effects. Unfortunately, owing to their outstanding effect, they are frequently abused or misused in animal husbandry. There is an urgent need to develop a sensitive and reliable method for monitoring these drugs in animal feeds. RESULTS This work reported a new method of hydrophilic‐interaction‐based magnetically assisted matrix solid‐phase dispersion (MMSPD) extraction coupled with reversed‐phase liquid chromatography–mass spectrometry for simultaneous determination of carbadox and olaquindox in animal feeds. 3‐Trimethoxysilylpropyl methacrylate (γ‐MAPS)‐modified attapulgite (ATP) was crosslinked with γ‐MAPS‐modified iron(II,III) oxide (Fe3O4), 1‐vinyl‐3‐(butyl‐4‐sulfonate) imidazolium (VBSIm), acrylamide (AM), and N,N′‐methylene‐bis(acrylamide) (MBA) to synthesize ATP@Fe3O4@poly(VBSIm‐AM‐MBA) particles. The resultant particles were characterized by scanning electron microscopy, energy dispersive spectrometer, transmission electron microscopy, vibrating sample magnetometer, and Fourier transform infrared spectroscopy. Crosslinking of ATP into the magnetic particles has significantly increased the adsorption capacity of the particles. Under optimum conditions, the limits of detection (S/N = 3) were 0.3 μg kg−1 and 0.9 μg kg−1 for carbadox and olaquindox respectively. The intra‐day and inter‐day recoveries of the spiked targets in feed samples were in the range 83.5–98.3% with relative standard deviations of 1.0–8.3%. CONCLUSION With a simplified procedure and a low amount of sample, the proposed hydrophilic‐interaction‐based MMSPD method is not only useful for the determination of carbadox and olaquindox in feeds but also holds great promise for the analysis of other polar targets in solid or semisolid matrices. © 2021 Society of Chemical Industry.

“…The SPE adsorbent is a key factor affecting the extraction efficiency, and many kinds of porous materials have been studied for this purpose, such as graphene and other carbon-based materials, molecularly imprinted polymers, modied silicone, magnetic sorbents, etc. [5][6][7][8] However, SAs differ greatly in hydrophilicity and size and, thus, high recoveries are difficult to achieve for various types simultaneously. Therefore, there is considerable interest in developing new selective sorbents for extracting and isolating SAs from complicated matrices.…”
