PMID- 38500629 OWN - NLM STAT- PubMed-not-MEDLINE LR - 20240320 IS - 2046-2069 (Electronic) IS - 2046-2069 (Linking) VI - 14 IP - 13 DP - 2024 Mar 14 TI - Developing a novel magnetic organic polymer for selective extraction and determination of 16 macrolides in water and honey samples. PG - 8726-8734 LID - 10.1039/d4ra00496e [doi] AB - A novel magnetic organic polymer Fe(3)O(4)@SiO(2)@Tb-PDAN was designed and synthesized, which was used as an adsorbent for magnetic solid-phase extraction (MSPE) of 16 macrolides (MALs) in water and honey. The synthesized adsorbent was characterized using techniques including scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (XRD). Then several parameters of the extraction process were further optimized. Under the optimized conditions, an MSPE-LC-MS/MS method was established for extraction and determination of 16 MALs, which showed good linearity (r >/= 0.999), low limits of detection (0.001-0.012 mug L(-1) for water and 0.001-0.367 mug kg(-1) for honey) and satisfactory recoveries (70.02-118.91%) with the relative standard deviations (RSDs) lower than 10.0%. This established method was then successfully applied to detect MALs in real samples, which suggested that Fe(3)O(4)@SiO(2)@Tb-PDAN was a potential magnetic adsorbent for efficient extraction and analysis of MALs.
