Evaluation of mesostructured silicas with wormhole-like framework functionalized with hydrophobic groups as alternative sorbents for extraction of drug residues from food samples

Different mesostructured silicas were synthesized and functionalized with octadecylsilane groups under same conditions. All materials were characterized and evaluated as sorbents for simultaneous multi-residue extraction of veterinary drugs from bovine meat samples by solid-phase extraction prior to their chromatographic analysis coupled to tandem mass spectrometry. The results obtained were compared to select the material with the highest extraction potential to achieve this purpose.
